Yeah, thanks for having me. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>We have lots of ground to explore, and I thought we would begin with a book that had a spot on my bookshelf when I was a kid. It seems like you and I may have found it at the same time, but you did a lot more with it than I did. The author is Robert O. Becker. Is that enough of a cue to tee it off?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, I think it is, I think it is.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. What is the book, and why is it relevant?<\/p>\n<p><strong>Michael Levin: <\/strong>I\u2019m going to guess it\u2019s <em>The Body Electric<\/em>.<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s right.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, yeah, yeah, yeah, it\u2019s very relevant. I discovered it in an old bookstore that my dad and I visited when I was in Vancouver, Canada, for the World\u2019s Fair in \u201986. And I found this thing, and it\u2019s a patchwork of a number of different things. He was into applied field of dangers and things like that. But I was just stunned with all the references to prior work that revealed to me that the kinds of things I\u2019d been thinking about were actually real and that people had investigated it.<\/p>\n<p><strong>Tim Ferriss: <\/strong>And that book, I guess Dr. Becker was an orthopedic surgeon, and he was effectively penning a scientific memoir, describing experiments involving salamanders and other animals, exploring the role of electricity and many, many different aspects of biology. How would you define, for folks, bioelectricity? What is a helpful way to define that term? And then we\u2019ll probably hop to the video in a sense that introduced me to your work, which I will not be alone in citing, but let\u2019s begin with the definition. Bioelectricity. What is that?<\/p>\n<p><strong>Michael Levin: <\/strong>Well, bioelectricity, in general, is the way that living systems exploit physics, in particular, the physics of electricity, to do the amazing things that living systems do. And there are, roughly speaking, two kinds of bioelectricity. There\u2019s the familiar kind, which is studied by neuroscience. And so this is the electrical activity of the cells in your brain. And I think everyone has a rough understanding of the fact that the reason you know things that your individual neurons don\u2019t know and that you have beliefs and the preferences and so on that are more than just any of the neurons in your head is through this amazing cognitive glue that electricity provides. It binds your neurons into a collective intelligence that underlies our mind. And so that\u2019s the bioelectricity that everybody\u2019s familiar with.<\/p>\n<p>And then there\u2019s the other kind, also called developmental bioelectricity, which you can get to by asking about, but where did the brain come from, and where did it learn those amazing tricks? And very quickly, you realize that, wow, some of these things have been around for a very long time, long before we had brains and neurons. And that the question of what does your body think about, and before it has a brain, how does it use electricity is the study of developmental bioelectricity.<\/p>\n<p><strong>Tim Ferriss: <\/strong>The video that I was referencing, you will not be surprised to hear, was an older TED Talk and then subsequent interview on stage, and that was sent to me by Adam Goldstein, who\u2019s now at Softmax. And that was probably several years ago, I would say at this point that it was sent to me. Could you perhaps \u2014 and I know a lot has happened since, but could you describe some of the experiments that you covered at TED to give people an idea of how this becomes tangible, this conversation of bioelectricity becomes tangible?<\/p>\n<p><strong>Michael Levin: <\/strong>When we look at biology, we see lots of amazing things. For example, in a salamander, if they lose a limb, they regenerate the limb, and they stop when it\u2019s complete. And in fact, there are many other interesting, these kinds of things that when anybody looks at it, the first thing they ask is, \u201cHow does it know to do that?\u201d<\/p>\n<p>And one of the things I discussed in that video was if you scramble the craniofacial organs of a tadpole, they still make a pretty normal frog. They sort themselves out, they move in new paths until they get to a normal frog face, and then they stop. And so anybody sees that, and immediately the question is, \u201cOkay, but how do they know what a proper frog face looks like? And if you do know, then how do you know how to get from here to there? How do you navigate?\u201d<\/p>\n<p>So the way we\u2019re all taught in biology is that that\u2019s a bad question. We are told none of these things know anything. They are mechanical machines that roll forward according to rules of chemistry. And in the end, some cool stuff happens, and we\u2019ll call it emergence and things like that, and complexity science will catalog them, but don\u2019t worry, none of these things actually know anything, that\u2019s just what they do.<\/p>\n<p>And so what I was trying to describe in that talk is this idea that, well, actually, the idea that chemical processes can in fact know things, it\u2019s not magic, it\u2019s not mysterianism. We are chemical processes that know things, and we\u2019ve had, for many decades, mature science of \u2014 including cybernetics and control theory and things like that \u2014 a mature science of figuring out how it is that machines of all different kinds can know things and they can have goals and so on.<\/p>\n<p>So what I tried to show in that talk are some examples by which the living tissues, for example, flatworms that are cut into pieces and every piece has to figure out \u201cHow many heads should I have? Where do the heads go? What should the shape of my face be?\u201d These kinds of things, that in fact they do know, and the way they know is because they store memories, and maybe not shockingly, although it\u2019s certainly shocking to a lot of folks, the way those memories are stored is in an electrical network that is very similar to the way that we store our goal-directed behavioral repertoires in our brain and that these things are widely spread. And so regeneration, cancer suppression, and cancer repair and remodeling, birth defects and birth defect repair, all of these things are extensively using electrical pattern memories, and we now have a way to rewrite those pattern memories.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I\u2019ve been so excited to have you on the show because I am an intrepid muggle, blindly, half blindly exploring science to the extent that I can. And every once in a while, I\u2019ll share a resource like I did recently, this multi-part series called <em>The Gene<\/em>. This is a Ken Burns-produced documentary about genetics, the history of genetics, starting with Mendel and so on, working all the way up to modern biotech. But the underlying framework for that entire series is DNA as master copy, let\u2019s call it, then RNA, then protein. And that\u2019s kind of how it works, right? You have this blueprint that is executed upon, and that produces what we see in the world on some level.<\/p>\n<p>But as I understand it, you, by manipulating bioelectricity, have produced, for instance, animals that have two heads that that trait persists over generations, and maybe I\u2019m getting the specifics wrong, but that is not by virtue of manipulating DNA. And I\u2019m just wondering if I\u2019m, first of all, getting that right, but secondly, what that says about how we might be revising our understanding of biology and what the textbooks might look like five or 10 years from now or further out.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, you\u2019re not wrong. I could list any number of scenarios that we and others have studied in which the genetics not only don\u2019t tell the whole story, but in fact, tell a fairly misleading story. And the way that I would describe it, and there are two pieces to this, and I\u2019ll do the simpler piece first, and then we can talk about the other piece. The simpler piece is really we can get there by thinking about the distinction between software and hardware.<\/p>\n<p>And by the way, I should preface this because some people get really upset about this. I am not saying that the current way that we think about software and hardware is sufficient to get everything we need from biology. It does not cover all of biology; it covers one important piece of biology. Reprogrammability is really critical. And so if you wanted to make that same movie about computers, for example, you could make a movie that basically goes electric fields, silicon and germanium, and transistors, and the flow of energy through circuits, done, right? That could be your movie.<\/p>\n<p>And it\u2019s not an unimportant part of the story; it\u2019s a very important part of the story, but the critical part that that doesn\u2019t get to is that\u2019s the hardware. And in fact, that\u2019s what the genome does. So the genome tells every cell what the hardware is going to be. So the genome gives every cell the little, tiny protein-level hardware that it gets to have. But now comes the other interesting part, which is the reprogrammability. And we\u2019ve known for a very long time now that if your hardware is good enough, and the biological hardware is more than good enough, then that hardware is reprogrammable.<\/p>\n<p>So what happens, just as an example, what happens in these flatworms, these two-headed flatworms that you were referring to, the standard \u2014 the flatworm has a bioelectric memory in it that says \u2014 and we can see it. I\u2019m saying these things because we can now see these memories and we can rewrite them at will. So this is now actionable in the lab. It has a bioelectric memory that says one head.<\/p>\n<p>That memory is not genetically encoded. What is genetically encoded is a bunch of hardware that when you first turn on the juice, it basically acquires that memory as a default. When you buy a calculator from the store and you turn on the power, they all say zero. Reliably, 100 percent of the time, they all say zero. Great. But that zero is not the only thing that that circuit can do. As you find out very quickly, they can store memory and do all these things. The genetic hardware of the worm is very good at making sure that every worm starts out with a very specific \u2014 it\u2019s a little bit, I think, related to instinct and how certain birds are born knowing how to make nests and things like that. The hardware has defaults, and by default, one head, but the hardware is reprogrammable.<\/p>\n<p>So what we were able to do is go in and identify the memory that actually says how many heads, and we can change it. And when you change it, you don\u2019t need to change the hardware, you don\u2019t need to change the genetics any more than when we form new memories, you don\u2019t need to change the genes in your brain to form new memories. I always say to people, \u201cOn your laptop, if you want to go from Photoshop to Microsoft Word, you don\u2019t get out your soldering iron and start rewiring. It\u2019d be laughable if you had to, but that\u2019s how we used to do it. In the \u201940s and \u201950s, you programmed a computer by pulling and plugging wires, but you don\u2019t do that anymore because it\u2019s reprogrammable. And that\u2019s what the biology is.\u201d And so that\u2019s the first thing.<\/p>\n<p>And the second thing, just very quickly, and we can get into it if you want, is that the cellular intelligence that exists not only is reprogrammable, but it is actually creative in the sense that it interprets the DNA. And we can talk about this. It doesn\u2019t blindly do what the DNA says, and this is a deep thing because it\u2019s the way our cognition works too, it interprets memories in a way that is improvisational. It does not simply follow what they say, counter to what we all learn.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. So I\u2019m going to come back to how the textbooks might be revised question in a minute. But before we get there, you said we can see memories. So this is empirically demonstrable in the lab. What does it mean to see those memories? What does that actually mean and look like? And then secondly, with the flatworms with the two heads, why does that persist if it does into future generations?<\/p>\n<p><strong>Michael Levin: <\/strong>What we can see directly are the bioelectrical properties of tissues. And we\u2019ve developed tools using voltage-sensitive fluorescent dyes. And so that means you take your embryo or your tissues or whatever you\u2019ve got, and you soak it in this special chemical that glows different degrees or different wavelengths depending on what the local voltage is.<\/p>\n<p>And so back in the olden days in electrophysiology, you had an electrode, then you would have to poke a little needle, and you would poke every cell, and you would get the voltage reading. We don\u2019t need \u2014 I mean, of course, we still do that for certain purposes, but what you can now do is get a full map of the whole tissue all at once. And in fact, you can make movies of it and watch it change over time. And we have these amazing videos of embryos changing their electrical activities over time. It\u2019s basically like what neuroscientists do when they do imaging in brains, but we can do it in the rest of the body. So there, what you see are the electrical patterns.<\/p>\n<p>Now from there, you have to do a lot of experiments to prove that what you\u2019re looking at are in fact memories. And there are many different kinds of things we do, but functionally what you have to show is that you can decode the electrical pattern that you\u2019re seeing and show that what it encodes is the future set points towards which the cells will work. In other words, I can take a one-headed worm, I can change the voltage pattern. It\u2019s still a one-headed worm, but it\u2019s internal representation of what a correct worm should look like now says two heads. You don\u2019t see it because it\u2019s a latent memory, but when you cut the thing into pieces, now what the cells do is consult the memory, and they say, \u201cOh, two heads,\u201d and then they build two heads, and you get your two-headed worm. So you don\u2019t know right away. When you\u2019re first looking at it, you don\u2019t know that that\u2019s a memory. You have to do experiments to prove that that\u2019s what it actually is.<\/p>\n<p><strong>Tim Ferriss: <\/strong>And then the persistence, the durability over generations?<\/p>\n<p><strong>Michael Levin: <\/strong>The process of regeneration and repair in general is a kind of homeostatic process. So it\u2019s like a thermostat. You have a set point. If the temperature gets too low, it tries to go up, if it gets too high, it tries to come down, it tries to keep a certain \u2014 that is exactly what happens in the body, which is anatomical homeostasis. So cells come and go all the time. So we\u2019re a ship of feces in many ways. So cells and materials come and go. Sometimes drastic kinds of injuries for animals that regenerate past them. Embryogenesis, I mean, look, half our population can regenerate an entire body from one cell. I mean, that\u2019s amazing. That\u2019s an amazing development. Embryonic development is an incredible example of regeneration, the whole body regenerating from just one egg cell.<\/p>\n<p>And in all of those cases, what needs to happen is just like a thermostat has to remember what\u2019s the right set point, there has to be a memory mechanism that stores it. And so the electric circuits in the body that store these patterns, they have a memory property as well, such that when you change it, it stays.<\/p>\n<p>Now sometimes there are multiple memories. And so we\u2019ve done things like, for example, in these flatworms, there are different species that have different shaped heads: round ones, triangular ones, flat ones. We\u2019ve shown that you can take a worm, change the bioelectrical signaling and get it to grow a head of a different species. But the fun thing about that is it grows the head of a different species. You haven\u2019t touched the genetics, by the way. Again, the genome\u2019s totally wild type.<\/p>\n<p><strong>Tim Ferriss: <\/strong>It\u2019s so wild.<\/p>\n<p><strong>Michael Levin: <\/strong>Right, but right, but it\u2019ll grow the head of a different species, and it\u2019ll stay there for about 30 days. And then it goes back to its origin, it\u2019s not permanent. The two-headed thing is permanent, that never changes. But the head shape, after about 30 days, they go back. And so clearly there are multiple, there\u2019s more than one. There\u2019s some kind of metacognitive thing that says, \u201cYeah, I know you thought that was your memory, but actually that\u2019s wrong.\u201d So it overwrites some kind of error-correction thing, which, that one, we haven\u2019t cracked yet. So there are layers upon layers.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. So for people who are listening and wondering how this translates or might translate to humans, I want to get there, but I\u2019m going to bridge to that simply by saying that this topic of bioelectricity has long been interesting to me. I mean, it\u2019s been interesting to humans for a very long time, going back to slaves in ancient Rome, stepping on electric eels and finding relief from gout, but in a more modern incarnation, I had Dr. Kevin Tracey on the podcast some time ago who was \u2014 he\u2019s incredibly well-sited, played a part after his experiences with patients with septic shock, identifying TNF-alpha and a lot of subtleties around that and has developed hardware in this case. I mean, they\u2019re programmable, but for vagus nerve stimulation, predominantly for, at this point, autoimmune disorders like rheumatoid arthritis and so on. But you can see some incredible, incredible clinical effects, and we\u2019re just touching the tip of the iceberg.<\/p>\n<p>So I\u2019m wondering, it took a long time to get here though, even with something that is relatively, I would say, straightforward to identify, which is the vagus nerve, AKA vagus nerves, these intercontinental cables running down either side of the neck with 100,000 fibers on either side. So in this case, we\u2019re talking about flatworms. We could certainly talk about other species that are known for regeneration, but broadly speaking, what might this mean for humans? How might this be applied to humans? Do humans have this programmable layer just as some of these other species do? What might therapeutics or morphoceuticals or otherwise look like?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, yeah, yeah, no, and that\u2019s a great connection. Yeah, Kevin\u2019s work is amazing. I was just talking to him a couple of weeks ago.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Oh, nice.<\/p>\n<p><strong>Michael Levin: <\/strong>It\u2019s awesome stuff, yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Great guy, great guy.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, he really is. Right. So a couple of things to explain why this is relevant to humans, and then I\u2019ll give you three broad areas of application. The reason it\u2019s absolutely relevant to humans is that we are all basically built on fundamentally the same principles. People have this idea that, well, frogs are a lower creature, but we\u2019re mammals. And once you get past yeast and things like that, we are all roughly the same. As far as this stuff goes, these kind of electrical signals were \u2014 evolution discovered them around the time of bacterial biofilms, very long ago. And so this is all very well-conserved.<\/p>\n<p>And for that reason, for example, there are human mutations in ion channels that are birth defects. So if you mutate ion channels in humans, you get birth defect just like we see in frog and chicken, zebrafish, and things like that. So those are all well-conserved.<\/p>\n<p>And with David Kaplan, who\u2019s a collaborator of mine at Tufts, we\u2019ve done a bunch of work on bioelectrics of human mesenchymal stem cells. So this stuff works, for humans as well. It is not some frog or flatworm specific thing. This is very, very broad.<\/p>\n<p>I should say, this is a disclaimer I always have to do, you mentioned morphoceuticals. So there are a couple of spinoff companies that have licensed some of this technology, so I need to say that as a disclosure. So one is specifically called Morphoceuticals. This is a company that is pushing forward our limb regeneration work in bioelectrics. And then there\u2019s also this other company called Astonishing Labs that is doing some of this stuff in aging and so on.<\/p>\n<p>So having said all that, I firmly believe that these things are heading for clinical application in humans, and probably not that far off, I hope. Here are the three applications. So the first application is birth defects. So we have shown that we can repair a number of different birth defects of the brain, the face, the heart, what else, the gut, these kinds of things by restoring correct bioelectrical patterns in vivo. And so this is now in animal models. We are moving, of course, to more clinical kinds of things. And I hope in the future this will absolutely be of human application. So birth defects is one. Regeneration is another.<\/p>\n<p>The name of the game here is communicating with the cells. This is not about stem cells or gene therapy or scaffolds made of nanomaterials. Those are all tools that might be useful, but the real trick here is to communicate to a group of cells, what do you want them to build? And that\u2019s what the bioelectric code is all about; it\u2019s about communicating to the collective, to the cellular collective. And so we\u2019ve done work on limb regeneration, we\u2019ve done work on inducing whole organ formation, eyes and things like this. So I think there are going to be massive applications hopefully clinically in restoring damaged and missing limbs and other structures like that.<\/p>\n<p>\u00a0And then the third thing is going to be cancer, so something else, and we can get into what the more profound aspect is, but the bottom line is that cancer fundamentally involves an electrical dysregulation among cells. I\u2019ll just say it and we can unpack it later, but it\u2019s basically a dissociative identity disorder on the part of the cells. It\u2019s literally a disorder of the cognitive glue that binds individual cells towards large-scale purpose where large-scale purpose, I mean building organs and tissues and things like that, as opposed to being amoebas and doing amoeba-level things. So cancer is another thing.<\/p>\n<p>And we\u2019ve shown again in these animal models, both that we can detect incipient tumor formation and we can prevent, and normalize tumors after they form by restoring, not by fixing the DNA if there is any DNA issue, which doesn\u2019t have to be, not by killing the cells with chemotherapy, but by electrically reconnecting them to the group such that they can form, again, a memory of what they\u2019re supposed to be doing. So those three things, regeneration, birth defects, and cancer, I think are going to be of great value in humans.<\/p>\n<p>Now there\u2019s also issues of aging. So we also have an aging program in our lab and looking at why it is that over time cells forget how to upkeep a proper organism. And we have some interesting thoughts about that as well.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Well, let\u2019s dive in. I\u2019d love to hear more about the interesting thoughts on aging. And then we\u2019re definitely going to get to cognition, which is \u2014 I mean, that can go in a lot of directions, but let\u2019s start with the aging piece. What are some of the implications or experiments or just maybe conceptual frameworks that are due as a revision of what we\u2019ve thought to date?<\/p>\n<p><strong>Michael Levin: <\/strong>First of all, one of the things that we\u2019ve seen is that, and, by the way, this is fairly recent work. So this is in no way is this the final story. This is just what we know now. I\u2019m sure this will be updated. Over time, the electrical pre-patterns that tell the cells and tissues what large-scale structure we\u2019re supposed to look like, they get fuzzy, they degrade over time. And so much like what we do with birth defects is we try to reinforce the correct patterns. And this is one of the ways we\u2019re addressing aging as well, is by reinforcing these patterns.<\/p>\n<p>Now one question you might ask is why over time are these things getting fuzzy, what\u2019s going on? And there are a couple of schools of thought. One is that this is the consequence of accumulated noise and damage, so molecular damage entropy, basically. Over time, you just accumulate damage, and everything gets degraded over time. And then there\u2019s also these kind of \u2014 what they call programmatic theories where basically the idea is that you\u2019re programmed to age. For whatever reason, evolution has favored a decline and death.<\/p>\n<p>So we have an interesting third alternative to offer, which is the following. And we did a simulation experiment where we had a virtual body where the cells cooperate together to build an embryo, and so they work really hard to work together. They build to a particular pattern memory, so this thing I\u2019ve been telling you about, they build. And then I said, \u201cLet it run. Just leave it alone, and let it run.\u201d<\/p>\n<p>And so what you see is something very interesting. They work really hard together, and they make the correct body. Then it stays that way as they defend it, and then it falls apart, and it begins to degrade.<\/p>\n<p>Now what\u2019s interesting is that in our simulation, there was no evolution for a limited lifespan, there was no noise, there was no damage; it was perfect, everything was perfect, and still, it degraded. Why would it do that? I had this interesting thought, and I\u2019ll back into it this way: just imagine this standard Judeo-Christian version of Heaven. So you get to Heaven, and you get there, let\u2019s say you, your pet snake, and your dog get to Heaven. So okay, everything is great, there\u2019s no more damage, there\u2019s no decay, nothing is damaged, everything is great, everything\u2019s fantastic. For the next trillion years, what happens?<\/p>\n<p>So the snake may be fine doing snake things for every day is the same as every other day, may be fine. The dog, not sure. Probably okay chasing rabbits on the farm, may be fine for forever, basically. The human though, what do you think? I\u2019d be interested in your thoughts. What are the odds that a human cognitive system can be sane for an infinite \u2014 okay, I\u2019ll keep myself busy for the first 10,000 years, maybe 100,000 years, but a billion years in, are we still sane? What happens? What do you think? What do you think would happen?<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s interesting. Well, if I\u2019m hearing you correctly, I don\u2019t really have a passing through the Pearly Gates timeline prediction for the half life of sanity, but if I\u2019m hearing you correctly, that the biological programmed, I mean, death, I suppose, is basically to \u2014 intended to ensure biological death before insanity. Am I mishearing that?<\/p>\n<p><strong>Michael Levin: <\/strong>Well, so maybe. That\u2019s not the claim I was going to make, but it\u2019s not impossible.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Not a claim, but I guess I\u2019m trying to squint and look through the exercise.<\/p>\n<p><strong>Michael Levin: <\/strong>What I took away from that work that we did was the following: you have a goal-seeking system that has met its goal. It\u2019s achieved the goal. It made the body was supposed to make. The error falls to zero, everything is great, hangs out there for a while, but what does a goal-seeking system do when there are no new goals? Because we\u2019re looking at a system that may or may not be able to give itself new goals. I mean, cognitively, I think we can, but it\u2019s not clear yet that this system can do that. And so what we were able to do is we were able to give it new goals by having interventions and going back in and saying, \u201cOkay, now this is your new pattern,\u201d and it will do that.<\/p>\n<p>But I think part of the, you could call it the boredom theory of aging, basically, not cognitively, somatically. If your body cells over a long period of time, they\u2019ve completed their job, they\u2019ve created a body during adulthood, but at some point they start to degrade. The cells don\u2019t degrade; the collective does, the cohesion, the alignment between them because there\u2019s no longer a common goal. I mean, this is what makes for an embryo or a body as opposed to just a billion independent cells, is they\u2019re all aligned towards the same set point, towards the same goal.\u00a0<\/p>\n<p>And so when that isn\u2019t there, regeneration, repair, maybe remodeling becomes something else. I don\u2019t know how. Maybe you need to change up the body every once in a while. That\u2019s also a possibility. Planaria do it. Planaria are immortal.\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>And planaria are the flatworms we were talking about earlier?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, the flatworms. Yeah, yeah, they\u2019re immortal. Every two weeks, they rip themselves in half and regenerate, so they give themselves a challenge every two weeks. And so they\u2019ve been that way for half a billion years or so. And I think that we can see evidence of this.<\/p>\n<p>For example, if you look at \u2014 there\u2019s a way to look at the age of certain genes, the evolutionary age of genes to see when did they show up. The gene expression of a young person, all the cells are in \u2014 all the different tissues have the same idea of what evolutionary stage they are, meaning in a human. When you look at old tissue, and this is something we just published recently, when you look at, we call it atavistic dissociation, when you look at the tissues of old age, the genes that they express start to float backwards in evolution. And they\u2019re discordant, they\u2019re out of sync. So your liver versus your neurons, they may all start to get different ideas in terms of the genes they express, of where on the evolutionary tree they are. So again, it starts to float off. In the absence of a compelling set point or goal state, all the subunits start to sort of float off and do their own thing. And this is, I think, an important component of aging.<\/p>\n<p><strong>Tim Ferriss: <\/strong>So if you were put in charge of, for lack of a better term, the Manhattan Project style initiative related to aging, that was your sole directive, was to really do a deep dive with the intention of developing some type of therapeutic for humans, what might that look like? I mean, for all intents and purposes, infinite funding, but you have the resources, you can get the talent. Where would you take it, if you had a similarly pressing deadline? And I\u2019m not asking for the impossible, but if you had a reasonably tight deadline by which you needed to try to come up with something, where would you take it? How would you think about it?<\/p>\n<p><strong>Michael Levin: <\/strong>Tight deadlines for aging are tough, because you\u2019re not going to know for decades whether your thing works.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, right.<\/p>\n<p><strong>Michael Levin: <\/strong>No, but I get the idea. This is what I would say. I think that fundamentally, I think that aging, cancer, birth defects, lack of regenerative repair throughout our lifespan, all of these kinds of things are downstream of one fundamental pressure point, that if you solve that, all of these things get solved by side effect. And that is regeneration.<\/p>\n<p>More specifically, that in turn is, everything there hangs on the cognition of groups of cells. In other words, how do groups of cells know what to build, when to stop? How do we communicate with them, and what kind of intelligence do they have? And I\u2019m being very specific about this. When I say they have intelligence, I don\u2019t mean complexity. I don\u2019t mean some sort of linguistic project where I\u2019m going to take things that are beautiful and fascinating, and I say, \u201cWell, that\u2019s the intelligence of life.\u201d That\u2019s not what I mean. I\u2019m using a very specific definition of intelligence, which is what behavior scientists use, which is problem solving, memory, different degrees of a cognitive light cone of goal-directed, the size of your goals, things like that.<\/p>\n<p>So specifically, figuring out what are the competencies of the living material that we\u2019re made of and how do you communicate new goals to them? There are lots of amazing people in the aging field doing interesting things and that\u2019s cool. If I had a lot of money specifically for aging, I would put everybody on that question. I would say, you\u2019re not studying aging. What you\u2019re studying is the goal-directedness of multicellular systems. Figure out how they know what to do and how we communicate goals with them. If you solve that, all of these other things get taken care of as a side effect.<\/p>\n<p><strong>Tim Ferriss: <\/strong>What might an example or sample new directive be? To give human cells or groups of cells a new goal, what might that new goal look like?<\/p>\n<p><strong>Michael Levin: <\/strong>I\u2019ll give you an example, and then we can talk about what the human case might look like. What we can do is, we can take a frog embryo and induce a particular electrical pattern somewhere in the body that we already know, that pattern codes for make an eye. That\u2019s how the other cells interpret that pattern. It means make an eye. Very interesting in the sense that we don\u2019t have to say which cells do what. We don\u2019t have to say which genes you need to turn on. These are all micro level details. We don\u2019t need to worry about them, because the material is competent. Just like when I\u2019m talking to you, I don\u2019t need to worry about how your synaptic proteins are going to \u2014 you\u2019re going to take care of all of that. All I need to do is give you the prompt, and vice versa, and we\u2019re having this amazing conversation. But our hardware takes care of all the molecular details. And the same thing here.<\/p>\n<p>So, we provide a bioelectrical pattern that says make an eye here, and the cells make an eye. Now, the first thing that happens, it\u2019s interesting. The first thing that happens is, there\u2019s a battle of worldviews that takes place. The cells try to get \u2014 we inject a few cells. They tell their neighbors, \u201cLet\u2019s make an eye.\u201d The neighbors actually say, \u201cNo, we\u2019re supposed to be skin or gut. Don\u2019t do it.\u201d And sometimes they win and sometimes we win. And so the goal of regenerative medicine is to be as convincing as possible, so that you win 100 percent of the time.<\/p>\n<p>But in the cases where we are convincing, and we have amazing videos of cells like convincing each other to have different voltages and whatnot, they make an eye. And so, what you\u2019ve done is, you\u2019ve taken a bunch of cells that were going to be, for example, gut, and you\u2019ve now pushed them to be an eye. At a very high level, I don\u2019t know how to build an eye. I don\u2019t know all the genes that have to be turned on. You do that. I\u2019m telling you something at the level of organs, this is going to be an eye. The eye is of the right size. It has all the right layers to it. It is functional. So you can see out of these ectopic eyes, it\u2019s really, really amazing.<\/p>\n<p>And so that is an example of giving these cells a new goal. How do I know it\u2019s a goal? Because I did not micromanage you to do it. I was not there saying, \u201cTurn on this gene, turn on that gene.\u201d I gave you a far off set point, by the way, in a wild space that no individual cell knows anything about, the anatomical space of organ structures. No individual cell knows what an eye is, but the collective does. And they stop when it\u2019s done. I don\u2019t need to be there to tell them to stop. They stop when it\u2019s done.<\/p>\n<p>And so, this is autonomous goal-directed activity, and it\u2019s a navigation of anatomical space. And so, we can do this. And we can\u2019t make everything. We can make portions of the brain. We can make eyes. We can make, in some cases, limbs. We can make some other structures.<\/p>\n<p>So, in the human, you could imagine two ways to go, and I don\u2019t know which is going to be correct, and we need to do a lot of experiments in mammals to nail this down. One possibility is that it might be enough to simply reinforce the existing human pattern. Every so often, you would get like a tuneup that reminds all the cellular collectives what we\u2019re supposed to look like. That\u2019s one possibility.<\/p>\n<p>There\u2019s another possibility, and I don\u2019t know which is correct. I hope the first one is right, but I think it wouldn\u2019t be the end of the world if it\u2019s the latter. Maybe it really does get too boring with the same pattern, meaning that, okay, you can go a few hundred years with this reminding of the standard human pattern, but eventually you have to do something unique. Now, the planaria are telling us that actually, it\u2019s hundreds of millions of years that you can make the same thing, so I\u2019m kind of optimistic that you can do that. But let\u2019s say that\u2019s not the case.<\/p>\n<p>If that\u2019s not the case in humans, maybe you have some number of hundreds of years or whatever of the standard human body plan. But then if you want to keep going, you got to make some changes. What does that mean? Maybe you wanted some wings. Maybe you want some tentacles. Maybe you want a third hemisphere to crank your IQ. Maybe you want, I don\u2019t know \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>A third eye. Who knows?<\/p>\n<p><strong>Michael Levin: <\/strong>Sure, sure, sure. Infrared vision out the back of your head. I don\u2019t know. People email me all the time asking for all kinds of weird peripherals. So maybe, maybe at some point, it means that you\u2019ve really got to change things up a little bit, caterpillar, butterfly style. Maybe.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Wow. And just to come back to a piece that we covered through the thought exercise of the pet snake, the pet dog. Do you think we have evolved to die, or to age? I mean, if so, why? What might be a straw man argument for that? I\u2019m just curious. Yeah.<\/p>\n<p><strong>Michael Levin: <\/strong>There certainly are reasonable theories of why evolution wants you dead, and there have been a number of them. Overall, I think there may well be trade-offs of the kind that, for example, we\u2019re not going to put a lot of \u2014 evolution would not put a lot of effort into maintaining something if something else is going to go off and you\u2019re going to die anyway. So there are these ecological trade-offs.<\/p>\n<p>I\u2019ll give you an example of something like that. People ask, \u201cHey, why can\u2019t humans regenerate their limbs the way that axolotls can, and things like that?\u201d Nobody knows, but here\u2019s a plausible theory. Imagine, you\u2019re an early mammal, you\u2019re running around the forest, somebody bites your leg off. Now, you have a high blood pressure, you\u2019re going to bleed out. If you don\u2019t bleed out, you\u2019re going to walk around and grind that thing into the forest floor. It\u2019s going to get infected. You\u2019re never going to have time to regenerate. What you might do is scar, seal the wound, inflammation, so that you might live to fight another day, but you\u2019re definitely not going to have time to regenerate the way that an axolotl might, sort of floating around in water for three weeks or whatever.<\/p>\n<p>So basically, what you might say is that evolution just kind of decided that it\u2019s not worth it. It\u2019s never going to work. It\u2019s not worth it. And by the way, deer antlers. Deer antlers are the one amazing mammalian example of regeneration, plus the liver. I mean, liver regenerates. But deer antlers, it\u2019s a large adult mammal that regenerates this huge structure of fast \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>The rate of regrowth is just incredible.<\/p>\n<p><strong>Michael Levin: <\/strong>Crazy. Yeah. Centimeter and a half per day of new bone.<\/p>\n<p><strong>Tim Ferriss: <\/strong>So nuts.<\/p>\n<p><strong>Michael Levin: <\/strong>That\u2019s bone, vasculature, innovation. And you don\u2019t put weight on it. It\u2019s not load bearing. It\u2019s the one appendage that\u2019s not load bearing. So anyway, why I\u2019m saying that is because you can imagine evolutionary trade-offs like that, where evolution just didn\u2019t bother optimizing for long age. You can imagine that. But fundamentally, I do not believe that we are inevitably mortal. I think that at some point, if we knew what we were doing, if we had appropriate regenerative medicine, I don\u2019t see any particular reason why we have to age and die.<\/p>\n<p>And then you face interesting questions about, for example, mental plasticity. We all know with advanced age, people get a little less plastic mentally, that kind of stuff. Is that a hardware problem or a software problem? We don\u2019t know. If you had somebody with a physically young brain at 100, would they be like an 18-year-old in terms of their ability to take on new ideas and focus and pay attention, whatever? Would that still stay? Or is there some kind of a cognitive, I don\u2019t know, a tiredness that happens, that is not a hardware issue? I don\u2019t think we know, but we need to find out.<\/p>\n<p><strong>Tim Ferriss: <\/strong>So I was going to ask you about computer science and AI and concepts that you would like biologists to learn. Well, let\u2019s start there. And then I\u2019m going to ask a question that might destroy any shred of respect that you have for me, but I\u2019ll save that for after this one. Do any concepts come to mind, because you certainly have spent a lot of time in computer science, that you wish you could require biologists to become familiar with, or to study? I\u2019m wondering about cross pollination between disciplines within which you\u2019ve spent a lot of time. It could go the other way as well, and this could be concepts from developmental biology or biology writ large that you think computer scientists should pay more attention to. But does anything come to mind for either of those?<\/p>\n<p><strong>Michael Levin: <\/strong>My original background is in computer science. Computer scientists are amazing, generally, at compartmentalizing, course graining, sort of modularizing, like hiding details and asking, \u201cOkay, but what\u2019s actually important here?\u201d And like black boxing things. Biologists generally think everything is important, and if you ask biologists, you\u2019ll get a list of 30 genes. And these are hard-won details, right? They\u2019re all important. But a computer scientist is like, \u201cOkay, but what is that actually doing?\u201d And that\u2019s really important. The most basic thing is this issue of reprogrammability, is that understanding that you get \u2014 and certain kinds of hardware is reprogrammable and why. That, I think, is really key.<\/p>\n<p>The other thing that I wish, and there\u2019s not really time, unfortunately, for almost any biologist to do this, but one thing I really love for my students to do, if they can, is to take a course in programming languages, and here\u2019s why. Not so they could code, that doesn\u2019t matter. It\u2019s not the coding aspect. What happens in a typical course of programming languages is that you spend \u2014 so let\u2019s say in a single semester, you\u2019ll spend three weeks doing different languages. And the thing about those languages, and maybe this is true of some human languages as well, but it\u2019s definitely true of computer languages, is that each language is a different way of looking at the world. You start off with something that makes sense and you\u2019re like, oh, step by step, you sort of tell it what to do. Okay. And then all of a sudden, bam, now there\u2019s this other thing where every piece of data \u2014 there\u2019s this language called LISP where every piece of data is also instructions, and you can execute any piece of data. Like, what? And then you get into this other thing, and it\u2019s functional programming. Now there are no variables. You don\u2019t get to have any variables. Everything is just a function call.<\/p>\n<p>And every time you do this, it sort of rips the foundation of your world out from under you, and it says, this universe works in a very different way than you thought before. Forget everything you knew before. Now you got to do this. And how are you going to solve this problem? Now there\u2019s recursion, or now there\u2019s no global variables, or whatever. And every time, and what it\u2019s really good for is that mental plasticity that reminds you that the way you think things are and the tools you think you have are not the only things in town. And so, when you do that in a lightning, and you have to get, things go fast and then the final exam comes and it\u2019s this other thing you\u2019ve never seen before. Being able to do that quickly, I think is super valuable, and I would love that to be more known in biology.<\/p>\n<p>But the final thing I\u2019ll say is, and this is, I think this is true, but just to be clear, this is very controversial and almost nobody else thinks this is true, so who knows? But the interesting thing that a lot of people, not just biologists, but a lot of people think is something like this. Okay, there\u2019s something going on with humans, maybe other animals, where biochemistry does not tell the whole story. You read the biochemistry textbook and you say, okay, that\u2019s cool, but there\u2019s something about my mind and my ability to solve problems in abstract spaces and my inner perspective and all this stuff. It\u2019s just not captured in these low level details. And so, that\u2019s a little disturbing. It\u2019s like, but what is that then, if it\u2019s not captured in the chemistry? Wait, where\u2019s that coming from?<\/p>\n<p>But don\u2019t worry, we have this other thing over here, which are machines. Dumb machines. Dead matter, dumb machines, algorithms, computers, and those things do only exactly what the algorithm tells them to do. They are perfectly captured by our formal model. So we have a formal model of chemistry and the rules of chemistry, and that we think does not capture what it is to be an entire, full-on human. But we have these other formal models of Turing machines and programming and code and mechanics, and those things capture exactly what the machines do. Those get the whole thing.<\/p>\n<p>I think, and this is the part that\u2019s very sort of controversial and not a widely shared opinion, I think that\u2019s false. I think our formal models never capture all of what\u2019s going on, and some of the craziest stuff coming out of our lab recently is showing how much, even in very simple sorts of machines, how much interesting novelty, not just complexity, not just unpredictability, but things that any behavioral scientist would recognize as some kind of a protocognitive capacity, shows up in even minimal systems where you don\u2019t expect it.<\/p>\n<p>And so, what I\u2019d like the biologists to sort of eventually, once we can show this widely, the biologist to understand is that the biological systems are amazing and awesome, but it\u2019s a kind of a larger degree, not kind, of what\u2019s already going on in inanimate systems. And for this reason, this is also kind of a crazy claim, is that I think the circle, if you make a circle of cognitive things and living things, I think cognition is wider than life. I think cognition predates life and I think it\u2019s bigger than life.<\/p>\n<p>Normally people do that the other way around. They say, here\u2019s the inanimate universe. Some chunk of that is living and some tiny piece of that is intelligent. I think that\u2019s exactly backwards. And that\u2019s something we need to understand, both on the biology and on the computer science end, is like, is there a distinction between what people commonly think of as living things and machines? Are there any actual machines in the sense that we like to think that there are? That\u2019s a deep set of questions for both fields in the future.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. That\u2019s a super tempting opening to take, and I might come back to it, but I wanted to take the opportunity, as promised, to destroy any credibility I might have with you and my audience.<\/p>\n<p><strong>Michael Levin: <\/strong>Great.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right, so I\u2019m going to try to give myself some air cover by going back. Sorry to drag you into it, Kevin, but to go back to Kevin Tracey, and also, actually, years before my interview with Kevin, one with Martine Rothblatt. And in both cases, Martine is just an incredible polymath on a lot of levels. People should look into Martine.<\/p>\n<p>But we were chatting, Martine and I, about a transauricular stimulation of the vagus nerve. And there\u2019s quite a bit of mechanistic debate around this. How many fibers are you hitting? Is it actually possible to do through the skin? Et cetera. But suffice to say, the clinical outcomes of certain types of placement, of certain types of currents on the ear, seem to produce pretty dramatic anti-inflammatory effects.<\/p>\n<p>And so, then that raised the question for me of, wait a second, do those maps I\u2019ve seen in Chinese medical offices have anything to them? Now, chatting with Kevin, he\u2019s like, \u201cWell, funny thing about that is that it was a Frenchman who actually put that together after taking a ballpoint pen and pressing on patients\u2019 ears, and then it made its way back to China.\u201d<\/p>\n<p>I don\u2019t know the full history, but as we\u2019re talking about bioelectricity, I have to ask, and again, this might be a dead end, but if you look at traditional Chinese medicine \u2014 I went to two universities in China and took a pretty close look at this at the time, in 1996, but is there anything to Meridians, Chi? Did they get anything right, or was it just coincidence? Is there really nothing defensible to it? I\u2019m just wondering if there\u2019s any overlap.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. I was wondering how wild you were going to get that with that question, like where that was going to go. That\u2019s not too bad. Okay, I don\u2019t know the epidemiological data on acupuncture and how it works in clinical trials or any of that stuff. I don\u2019t know. What I do know is that I personally, I know an amazing, there\u2019s a guy in Boston called Tom Tam, and I\u2019ve known him since the \u201980s, my whole life, since I was a kid. And he\u2019s treated me, he\u2019s treated my family. I\u2019ve seen people, advanced cancer patients in his clinic. Don\u2019t know anything about the wider epidemiological aspect of it. To me, as someone who\u2019s interested in practical results, I would say, I can\u2019t say anything other than 100 percent that I think there\u2019s something very powerful here, very significant.<\/p>\n<p>So the next question is, what are those meridians, and do they have any functional overlap with the bioelectricity that we\u2019re talking about? I don\u2019t know. We actually had, back in 2006, I think, we had a little bit of a collaboration with the New England School of Acupuncture to try to figure that out. I wanted an animal model. I wanted to see if we can do a frog model of acupuncture or something, and so on. It didn\u2019t work, for a number of reasons.<\/p>\n<p>The real answer is I don\u2019t know. But if I had to guess, what I would say is that whatever it is that acupuncturists are managing with their treatments are \u2014 it has the same relationship to the bioelectricity that the bioelectricity has to the chemical signaling. In other words, chemical physical protein signaling pathways, bioelectrical state, there\u2019s some other informational state. Maybe it has to do with the biomechanics of tissues. And again, disclaimer, I still get acupuncture. Vanessa Grimes here in Beverly, every month I get a tune up. I think it really works, so take it all with a grain of salt.<\/p>\n<p>But I don\u2019t think they\u2019re managing bioelectricity directly. I think they\u2019re managing something else, which is no doubt relevant to the bioelectric layer, because it then has to transduce through that to the rest of the body. But I suspect it\u2019s not bioelectricity per se. I suspect it\u2019s something additional. That\u2019s a guess on my part.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Cool. I\u2019m glad I asked. Thanks for answering, too. On the acupuncture side, I don\u2019t get a whole lot of acupuncture. And you can look at sham studies and so on where, yes, in the case of, for instance, one of my PTs in Texas, you can use something called dry needling instead for muscle spasms, and it\u2019s very, very effective. But then you can also conversely look at data in, say, canines, or pain control in animals, where, as far as we know, placebo is going to be pretty tough to defend.<\/p>\n<p><strong>Michael Levin: <\/strong>Well \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Well, maybe. I guess, you tell me. Maybe not. Or surgery with, I mean, this is probably not the right term, but sort of anesthesia via acupuncture, also pretty interesting. So, I don\u2019t know where to take that. I don\u2019t have any domain expertise, but it continues to be interesting, I suppose. And also, pregnancy data, acupuncture for conception, which may intersect with vagus nerve stimulation. Who knows?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. I mean, the deal with placebo, I don\u2019t see placebo as a confound. I mean, it can be if you\u2019re trying to calculate certain things, but I think it\u2019s kind of the main show in a lot of ways. And some of the placebo research, like Fabrizio Benedetti is one of my favorites, and he has a talk where he says, \u201cWords and drugs have the same mechanism of action.\u201d And it\u2019s amazing, because he actually does the experiments of giving patients drugs that he tells them what they are, and then he looks at molecular markers in their blood and in their cells, and yeah, they turn on the downstream, except that they didn\u2019t get any of the drug.<\/p>\n<p>So there\u2019s something very interesting going on here, and we already know \u2014 I mean, okay, if I were to come here and tell you that, \u201cHey, did you know that with the power of my mind alone, I can electrically depolarize up to 30 percent of the body?\u201d You\u2019d say, \u201cWhat is that? Yoga, mind matter? Mind, body, what kind of thing is that?\u201d I\u2019d say, \u201cNo, it\u2019s voluntary motion. We do it every day.\u201d So it\u2019s an amazing thing that nobody talks about.<\/p>\n<p>Think about this. You wake up in the morning, you have these very abstract, high-level goals. You have social goals, financial goals, research, whatever. And in order for you to do any of that, you have to get up out of bed. So what has to happen is these incredibly high-level, abstract intent has to change the way that calcium and potassium ions go across your muscle cell membranes. These abstract mental things have to change the chemistry of your body cells. We know that\u2019s true. Every time you lift your arm up or you take a step, voluntarily, that is what\u2019s happening. So we know that works.<\/p>\n<p>So if that works, why is it so bizarre to think that our other mental states might not affect, either through the electrical transduction of the nervous system, or through other non-neural bioelectricity or through other pathways yet, could affect ways that other cells act? It doesn\u2019t seem weird to me at all. It seems like it would have to be that way. But what we need to figure out is how it works and how to communicate. I think that\u2019s an incredibly powerful \u2014 if acupuncture is some kind of entry point into figuring that out, great. It\u2019s not a confound, it\u2019s a feature.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. I totally agree with the placebo not necessarily being a confound, as you mentioned, depending on what you\u2019re optimizing for measuring and so on. I mean, as someone who\u2019s funded a lot of basic science and clinical research involving psychedelic compounds, which are just notoriously difficult to blind. It\u2019s like, yeah, give someone a megadose of niacin plus X, Y, and Z or Ritalin or something like that. But generally, the control group knows that they are the control group. But that doesn\u2019t invalidate the research, right? It just points out maybe some methodological revision or tweaking that might be helpful. I want to \u2014\u00a0<\/p>\n<p><strong>Michael Levin: <\/strong>Well, sorry, just to add it, there\u2019s something else here that\u2019s really interesting, and I haven\u2019t seen anybody in the field, maybe you know folks that have looked at it. A lot of times, at least what I understand in some of Fabrizio\u2019s data, both for the efficacy and for the side effects, because there\u2019s the nocebo effect. People, they start, oh yeah, definitely headache or whatever. But what\u2019s interesting is, to me anyway, is that unless, if you\u2019re a scientist and I tell you that, okay, I just gave you an SSRI, you may know what the downstream steps are going to \u2014 if you\u2019re a regular person off the street participating in this study, now how do you know what the actual \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>That\u2019s the wild part, right?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>How do you actually implement the instructions?<\/p>\n<p><strong>Michael Levin: <\/strong>That\u2019s right. That\u2019s right. And I think actually, I think animal studies should actually be very \u2014 this is how we got here, is talking about animal placebo, because there are studies in experimental effects in animals, where \u2014 there are whole books on this where you do, in behavioral science, you do these experiments on rats, and whatever the experimenter believes is what the rats end up doing. They don\u2019t need to understand the placebo. They\u2019re going to do it anyway if the experimenter believes it, right? So, trying to understand some of these subtle cues and influences, and how does your body know things, I think, is like super, super interesting.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Okay, I can\u2019t let that one go. So, what do you think is actually happening there between the experimenter and the rats? I mean, is it just the subtle body language, et cetera, that\u2019s being transmitted to an animal who\u2019s perceiving that? That seems like a stretch, even as I say it, but I don\u2019t know what the alternative explanation would be.\u00a0<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>What might be a theory or two for what is actually happening?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, good question. I don\u2019t have a theory, but I will mention some things to think about. One of the remarkable things that living systems are good at is in credit assignment, in selective attention. So for example, there\u2019s this old work on biofeedback from, I think, the \u201970s, where they can show that a rat can generate a temperature difference of a few degrees Celsius between its ears if you reward for that. And so now, just think. And it doesn\u2019t take years of practice, it\u2019s pretty quick. And just think, you\u2019re a rat, you just got some reward. So let me see. While my tail was pointing north and my whiskers were kind of vibrating and my gut was doing this and my toes were \u2014 what the hell did I just get rewarded for?<\/p>\n<p>You would think, and this in computer science is called the frame problem, because trying to get robots and AIs to focus on the important thing. There\u2019s an old \u2014 I forget who did this example, but imagine there\u2019s a robot, and it\u2019s in a room with a bomb, and the robot says, \u201cOh, there\u2019s a bomb. I\u2019ve got to get out of here.\u201d And it leaves. Except the bomb was on a cart that was connected to the robot, so it goes with him, and of course, he blows up. So what does the next robot do? Maybe Dan Dennett, I don\u2019t remember. So the next robot is like, okay, okay, we have to have them consider all the options. So now this robot he goes in, so the robot\u2019s like, \u201cWell, let me see. The walls are pretty vertical and the paint is dry, yeah, and it\u2019s a 90 degree angle. Cool.\u201d And so by the time it\u2019s considered all these things, of course it blows up again. So that\u2019s no good. And so biologicals are amazing at knowing what to pay attention to, \u201cWhat was I just rewarded for? What was the thing I did, which I\u2019m never going to do again which turned out poorly?\u201d We don\u2019t know how that works. And that I think is going to be a major part of that puzzle that you\u2019re asking about.<\/p>\n<p>And I\u2019ll just give you an example from our work, flatworms. Again, planaria. We put planarian in a solution of barium. Barium is a non-specific potassium channel blocker. It blocks all the potassium channels. So that makes it very hard for cells to do their physiology, especially the neurons freak out. Their heads explode. Literally overnight, their heads explode. But as it turns out, so it\u2019s called deep progression is a way to put it, but basically the cells just explode.<\/p>\n<p><strong>Tim Ferriss: <\/strong>It\u2019s a very polite way to put it.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, yeah. It sort of deprogresses. But what we found is that \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>Net negative treatment in special ops assassination. \u201cOh, yeah. It\u2019s just a negative treatment, yeah.\u201d<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah, yeah. Basically it\u2019s a deprogression. But here\u2019s the amazing part. So you take the part that\u2019s left, the tail and the mid-body, you leave it in the barium. And within about 14 days, they grow a new head and the new head doesn\u2019t care at all about the barium, no problem whatsoever. So the new head is fine. So how is this possible?<\/p>\n<p>So what we did was a very simple-minded experiment. We took all the genes that a normal head expresses, all the genes that \u2014 and for sure, this doesn\u2019t have to be in the genes. This is just a simple thing we did to start with. And what genes does the barium-adapted head express? And we found less than a dozen genes that make the difference. Now think about this. planaria don\u2019t normally see barium in the wild. You don\u2019t have an evolutionary response to what happens when I get hit with barium. You\u2019re sitting there, I view that you have something like 20,000 genes. You\u2019re hit with this new stressor that you\u2019ve never seen before. How do you know which of those 20,000 genes are going to help?\u00a0<\/p>\n<p>I always visualize this as you\u2019re sitting in one of those nuclear reactor control rooms, there\u2019s buttons everywhere, the thing\u2019s melting down. You don\u2019t have time to start flipping switches sort of randomly. You\u2019ll be dead long before that. How did they zero in on the correct 12 things out of a space of 20,000 dimensions that they could have? It\u2019s a very high dimensional search problem. We don\u2019t know. Nobody knows.<\/p>\n<p>And that aspect of it, biology, finding solutions to problems they haven\u2019t seen before, knowing what\u2019s salient, figuring out what to pay attention to. There are aspects here that we haven\u2019t even come close to replicating in our engineering technologies. I think it\u2019s going to be part of all that.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Well, this is a pretty close hop to \u2014 and this is a term that has very specific meaning for you, so it may not be the right term for me to use, but cognition. Let\u2019s talk about human cognition in the way that most people would think about it. We have this big, big ball of fat inside our skulls. A bunch of magic seems to happen and we\u2019ve got these amazing tools. We\u2019ve got these MRIs, PET scans, et cetera, that we can \u2014 EEGs and so on that we can use to try to study the brain and what\u2019s actually happening. And my question is, and not to belabor this type of question, but it\u2019s just a forcing function for conversation, 10 years out, 10 years from now, how the textbooks, and textbooks may or may not even exist at that point, but how the teaching of neuroscience might have fundamentally changed as it relates to cognition.<\/p>\n<p>Because I look at, for instance, funding a lot of neuroscience over the last 10 years. And it\u2019s like, okay, sometimes the scientists are attracted to whatever the fanciest tools might be. There\u2019s some prestige in that. They produce a lot of beautiful images. You can slice and dice the data from a single study 15 different ways and get a lot of publications. And this is not something I could technically defend. I\u2019m left feeling, as a lot of people do, that there\u2019s something missing. It\u2019s not quite capturing the full picture, pun intended, not just with the MRIs, but with a lot of these tools that we\u2019re using.<\/p>\n<p>And I\u2019m bringing this up because of the comment you made about the gap between the biologics and current engineering. And this certainly relates to AI and so on, but I don\u2019t have the technical chops to understand quantum effects, but if I think about some of the cursory reading I\u2019ve done about quantum effects in olfaction, let\u2019s just say, smell. I\u2019m just left wondering what we might be missing fundamentally about how cognition works and also ties into, not to turn this into my own TED Talk, I\u2019ll try to wrap this up in a second, but having conversations with my friend, Kevin Kelly, who\u2019s the founding editor of <em>Wired<\/em> Magazine, who\u2019s an avid beekeeper and about just the collective memory of hives and properties that you would never be able to predict and that I\u2019m not entirely sure you can, at least at this point, engineer from the ground up. But how do you think our view of cognition, thinking, mind might change in the next five, 10 years?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. Okay. I want to talk about two things, one of which I\u2019m pretty sure is going to be very different in that timeframe, and another thing which is more fundamental that may take longer or may not.<\/p>\n<p>The one thing that I think for sure is going to change is that there\u2019s a thriving emerging field out there now called diverse intelligence. And this is the idea that biology, and as I\u2019ve been pushing it also non-biology, has been doing intelligence of different kinds long before brains and neurons appeared. It\u2019s been solving problems, navigating spaces, having memories, anticipating the future long before neurons appeared. The biggest barriers to this are these ancient categories that we got saddled with from pre-scientific times, this idea that everything is binary. People ask, \u201cIs it intelligent? Is it conscious? Is it this or\u2026\u201d That binary framing has been holding everything back for a really long time.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Is it holding it back because it\u2019s bifurcated between inanimate and animate? Or is it something else?<\/p>\n<p><strong>Michael Levin:<\/strong> It\u2019s the idea that it hides and it obscures the fact that we don\u2019t have a good story of scaling. Just two quick examples. When you go to court, there\u2019s this notion of an adult. We all know if you really think about it, nothing happens on the night of your 18th birthday, literally nothing, and that\u2019s A. And B, we don\u2019t actually have a good story of a scientifically grounded story of what does it mean to have personal responsibility? How does that change over time? How is it impacted by neurotransmitters, brain tumors, Twinkies, society, whatever? We don\u2019t actually have those questions answered, but you\u2019ve got to get traffic court done, or whatever. And so we\u2019ve just decided we\u2019re going to have this thing called adult and we\u2019re going to clock it on the 18. The car rental industry actually does better because they look at statistics and they\u2019ll say, \u201cNo, actually it\u2019s 25 is when you\u2019re more fully cooked is when you can rent a car,\u201d and so they do a little better, but regardless, the idea is that we \u2014 and we all say it\u2019s an adult.<\/p>\n<p>And so what those binary terms do is they obscure the fact that, yeah, but underneath, we actually still don\u2019t have a proper understanding of what\u2019s going on. And so by saying that something is or isn\u2019t intelligent, what you\u2019re basically assuming is that somewhere, some developmental biologists can tell you what happened from the time that you were an oocyte, a little blob of chemicals that presumably was well handled by biochemistry and physics, and then eventually, well, now you\u2019re the subject of physiology, and then eventually you\u2019re the subject of developmental biology. And then, oh, look, now you\u2019re the subject of behavior science. Oh, wait, psychoanalysis. So each of us made that journey. It\u2019s a smooth, continuous journey. Developmental biology offers no support for this idea that somewhere there\u2019s a bright light, flash of light and that, okay, now you used to be just chemistry, but now you\u2019ve got a real mind. That never happens.<\/p>\n<p>Because here\u2019s the other thing they do. If I were to say that it\u2019s a continuum, if cognition is a continuum from the most primitive passive matter to humans and above, what I could say is, \u201cI\u2019m going to take some tools from behavioral neuroscience and I\u2019m going to apply them to all kinds of weird things and see how that works out for me and that\u2019s how we\u2019re going to know what\u2019s cognitive and what\u2019s not.\u201d And this in fact is what my lab is doing. That project is very disruptive and there are a lot of people who really think that\u2019s crazy because what they will say is, \u201cLook, it\u2019s a category error.\u201d Brains and humans think. Cells and tissues can\u2019t think. How do you know? Well, because the way the word is defined.<\/p>\n<p>So what they\u2019ve done is they\u2019ve taken something that\u2019s actually should be an empirical experimental science, take the tools and see where they give you benefits and where they don\u2019t, but instead they\u2019ve made it into a philosophical or a linguistic project where these ancient categories that we got saddled with, \u201cOh, don\u2019t make a category error.\u201d That kind of thing, so I think it\u2019s very disruptive.<\/p>\n<p>So I think what\u2019s going to happen in the future is that all of the applications now that are coming out from Active Matter Research, from basal cognition, from work in slime molds and single cells and materials with learning capacity and all this stuff, we\u2019re going to realize, I think, this is again one of these claims, I think that neuroscience is \u2014 we\u2019re going to realize neuroscience is not about neurons at all, and that what neuroscience is really about is cognitive glue. Neuroscience is the question of what kind of architectures add up to larger-scale minds from aligned simpler components? Now, neuroscience has a lot to teach us about that because that\u2019s basically what they\u2019ve been studying, but I think the majority of them, not everybody, because we have all kinds of collaborators in this field who are doing something else, but the vast majority of traditional neuroscience think they\u2019re studying neurons, that this is something unique to these cellular systems that they\u2019re studying.<\/p>\n<p>And I think this field of diverse intelligence combines artificial intelligence and engineering and cybernetics and evolutionary biology and AI and exobiology and the search for alien life. All of these things are together asking what are actually the common threads of being an agent? No matter what your origin story, whether you were designed or evolved or engineered or evolved, or whether you were made of squishy proteins, or whether you were made of silicon or something else. Yeah, I don\u2019t know. I think science fiction prepares you for that nicely and for that kind of stuff to really have a broader conception of it. And so I think really understanding what neuroscience is actually about, I think, is going to be a massive change.<\/p>\n<p>And the final thing I\u2019ll say is, and this, I don\u2019t know how long it\u2019s going to take to, hopefully not that long, but you might remember this story that at one point I think in the late 1800s, I think it was Lord Kelvin who said that, \u201cYeah, physics is kind of done. There\u2019s just these two black clouds or something, but mostly it\u2019s just about more digits past the decimal point, but there\u2019s these two clouds.\u201d And the two clouds basically became quantum mechanics and relativity and all of that.<\/p>\n<p>And so I think neuroscience has a couple of black clouds, and I\u2019ll just describe one of them. We did a, Karina Kofman and I, she\u2019s amazing, she started as a high school student working with me remotely, we just did a review of this, clinical cases in humans of normal or above normal IQ while having very minimal brain volume. I\u2019m sure you\u2019ve heard some of these cases, but there are many to look at. Now, it\u2019s not that you can\u2019t add a bunch of epicycles to standard neuroscience and somehow try to squeeze these things into the mainstream paradigm. Maybe you can. But to me, the most important thing is that it doesn\u2019t predict that that should be possible. There\u2019s nothing we learn, at least that I\u2019ve ever seen in neuroscience courses that tells you that, \u201cOh, and by the way, yeah, you should be able to do all this with less than a third of the brain volume of a chimpanzee.\u201d<\/p>\n<p>So there\u2019s something going on here, which I think is really fundamental. It\u2019s one of these observations that you can try to sweep under the rug, but I think it\u2019s actually telling you that we have some very, very seriously wrong assumptions somewhere in the theory.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. It\u2019s exciting. It\u2019s super exciting. I mean, I\u2019ve looked at some of that research, or in some cases brain adaptations around severe injury, and they just raise a lot more questions than we can currently answer.<\/p>\n<p>This could be a quagmire I\u2019m about to create, but I\u2019m going to take a stab at it anyway. A lot of people talk about consciousness maybe in the same way that people argue about God without defining it very well, but then even the best intentions to define it can end up slipping on banana peels. But I am curious, you\u2019ve spent time with Daniel Dennett, who I think you mentioned a little bit earlier. We\u2019re talking about, and I think you can keep most people probably on the same page when you\u2019re talking about intelligence as very carefully defined in a specific way. And I\u2019m paraphrasing here from memory, so I apologize if I get it wrong, but goal seeking systems that maybe can satisfy those goals in multiple ways, maybe this is kind of along William James lines. Feel free to fact check that. But I\u2019m wondering where you go from there or how you think about consciousness. If you do at all, maybe that\u2019s just one of those terms that\u2019s like, well, it\u2019s like success or happiness. It\u2019s so poorly defined I don\u2019t spend a lot of time thinking about it because it\u2019s a dead end. But if that\u2019s not the case, how do you think about consciousness? Because as you\u2019re talking, and some people may have been thinking of this, they\u2019re like, \u201cWell, wait a second, is Mike a panpsychist?\u201d Where are we going here?\u201d<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. I\u2019m a, I don\u2019t know, some sort of super panpsychist or something. Okay, I don\u2019t think it\u2019s unimportant. I think it\u2019s a very important question. Big picture, I think it\u2019s really important. I\u2019m not a consciousness researcher and in my lab, we haven\u2019t done pretty much any experiments on consciousness, so I want to preface everything I\u2019m about to say by saying that, first of all, this is not something I typically work on. And the reason I don\u2019t work on it right now, and I do have some stuff cooking, but it\u2019s not ready yet for public consumption, the reason I don\u2019t focus on it now is that there\u2019s so much that can be done without delving into that, with a third person perspective on observable problem solving, cognition. And even that has been such a slog. I\u2019ve been at this for now 20 years and it\u2019s been so difficult to get people to shift in that way, that I don\u2019t need to get into consciousness to do the things that I need to do now. Nevertheless, and so for that practical sort of strategic reason, I haven\u2019t been talking about it except for when people ask.<\/p>\n<p>And so if you ask, I would say that for the purposes of defining what we\u2019re talking about now, I would say simply something like: first person perspective of the kind that makes my toothache really quite different in import than anybody else\u2019s toothache. There\u2019s something about my toothache that\u2019s quite different than when other people \u2014 it\u2019s terrible when other people have a toothache, but there\u2019s something different when I have it. And so that\u2019s, I think, the kind of thing that we\u2019re talking about here.<\/p>\n<p>So here\u2019s what I would say about it. First of all, again, I really can\u2019t understand how anybody can maintain a binary view about this, both on an evolutionary scale and on a developmental scale. If you think you are conscious, and I realize that some people don\u2019t even think that, but let\u2019s assume that we think that we are conscious, you have to tell me when that showed up in development. Development is slow and gradual and either the oocyte had something that got scaled up in some way, and then what we really owe is the story of scaling, which is what I think. Or some sort of people will say phase transition. And that\u2019s a fine hypothesis. You have to show me what the phase transition is and why I can\u2019t zoom into it because the nice thing about those graphs that goes like this, is that if you just stretch the horizontal axis, they all become smooth and flat eventually. So what exactly happened that you weren\u2019t conscious and then you became? I think that\u2019s a total nonstarter.<\/p>\n<p>So I think the question about consciousness is: what kind and how much, right? So let\u2019s just start there. And then I would say that there are roughly four reasons why people give each other the benefit of the doubt about consciousness. So the problem of other minds, how do I know that you\u2019re conscious? And there\u2019s usually four types of reasons that people give. What I can say is that if you like any of those reasons, for any of those four reasons, you should take very seriously, for example, the idea that other organs in your body have their own consciousness for those exact same reasons. For the same reason, we can dive into it if you want, but for the same reasons that you and I think each other is conscious you should take very seriously the idea that there are other parts of your body that are.<\/p>\n<p>Now, at this point, people usually say, \u201cWell, that\u2019s weird. I don\u2019t feel my liver being conscious.\u201d Right. Your left hemisphere that\u2019s verbal puts up a very nice story about how it\u2019s the only one that\u2019s conscious. And of course you don\u2019t feel your liver being conscious, you also don\u2019t feel me being conscious. That\u2019s because you are not that consciousness. But that doesn\u2019t mean that there aren\u2019t any number of other consciousnesses inhabiting your body and you would not have primary access to them. And some people disagree, but that\u2019s what I think.<\/p>\n<p>So I think that we should take very seriously the idea that certainly all kinds of other minimal biologicals have some degree of, I\u2019m not saying every cell is sitting there having hopes and dreams like we are, but little ones, little tiny ones. And so that I think I can say reasonably strongly.<\/p>\n<p>The thing that is a total conjecture is the following. Something that I\u2019ve said more recently, just this year I\u2019ve started talking about this notion of this Platonic space. And if you want to talk about that, we can get into it. But I think that in many ways, all the things that we are looking at, so bodies, computers, robots, embryos, the biobots, all of those things are in an important sense, thin clients. They\u2019re front-end interfaces for patterns, patterns of behavior, patterns of information processing, patterns of form and so on for patterns that come from a different space. They don\u2019t come from this physical space and we can dig into that.<\/p>\n<p>If that\u2019s the case, then what you could say is, and again, this is not something that, this is just conjecturing here. I\u2019m not saying this is useful in the lab yet or anything like that. I like to keep those things separate. But if you have to say something about consciousness, what you might say is that consciousness is, it\u2019s the point of view of the pattern projecting into the physical space. In other words, third-person observable behavior problem solving like normal science is what we see with each other doing within the space, but consciousness is the viewpoint of the pattern that is fundamentally, like you and I on that view and many other things are fundamentally patterns that live in this other space and we sometimes project through various interfaces, like physical bodies, robots, androids, whatever, machines, embryos. We sometimes project through these physical interfaces and consciousness is what it is like, the experience that it is like, to be one of those patterns projecting into space. That\u2019s one way you might think about it.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Could you explain that again as if I\u2019m a smart sixth grader very interested in technical stuff? And I suppose what I\u2019m trying to triangulate on is: are you getting into Donald Hoffman territory of reality as user interface? I\u2019d love to hear you explain the other space or not coming from physical space, just maybe to put it a different way.<\/p>\n<p><strong>Michael Levin: <\/strong>Sure, sure. Okay, let\u2019s run through it. So I think Don\u2019s work is very interesting. For the purposes of what I\u2019m about to say, we don\u2019t need to worry about it. Let\u2019s assume a perfectly conventional physics. I think Don\u2019s onto something I think for sure, but let\u2019s assume that we don\u2019t need to worry about that. A perfectly conventional physics. One thing that scientists nowadays like is a view called physicalism. Physicalism says that, \u201cLook, there\u2019s only one realm that we need to worry about. It\u2019s this physical realm. Physics tells us everything you need to know about this realm, and there it is.\u201d A lot of people like that. But I actually think that view is a non-starter for the following reason: there are all kinds of important facts that are simply not facts about physics. They are not discovered by physicists. They will never be discovered by physicists. They are not changed by anything we do in physics. And those are certain facts of mathematics.<\/p>\n<p>So for example, the exact value of E, the natural logarithm, the fact that complex numbers behave differently than quaternions that behave differently than octonions under certain \u2014 the truths of number theory, certain facts of topology and the distribution of prime numbers, you can\u2019t just dissolve the math department and hope that, \u201cDon\u2019t worry, the physicists will figure out why this is. This is not what they will ever do.\u201d The math department does things that are different and additive to what physics does.\u00a0<\/p>\n<p>And both in physics and biology, and I think in cognitive science too, there\u2019s an interesting phenomenon, which is that if you\u2019re like a five-year-old and you do that thing where you keep asking, \u201cBut why? But why?\u201d If you keep asking \u201cBut why?\u201d long enough, eventually you always end up in the math department. It\u2019s the damnedest thing. Imagine.<\/p>\n<p>Cicadas, they come out after every, whatever, 13 and 17 years or something they come out and you say, the biologist, you say, \u201cHey, why is that?\u201d \u201cAh, because that way they don\u2019t time their predators. Because if it was every 12 years, then every two year, three, or four years, sixth year a predator would get you, right? So 13 and 17.\u201d \u201cOkay, but that\u2019s cool. Why are those numbers so special?\u201d \u201cAh, they\u2019re prime numbers.\u201d \u201cBut why 13 and 17? Why isn\u2019t there one in between?\u201d \u201cNow you\u2019ve got to go to the math department because they\u2019re the only ones that understand why that is.\u201d So it\u2019s like this with everything. With physics, you keep digging, but why do the fermions do this or that? \u201cOh, because this amplitude has this symmetry group or whatever.\u201d So there\u2019s something interesting going on where even from the basic, most basic math that you learn in high school up through these very complicated things, there are a bunch of facts that are simply not facts of physics. Now, okay, so this I think is just how it is.<\/p>\n<p>Now from here, you have a choice to make. You could say, \u201cWell, these are just random regularities that are true in our world. It\u2019s just a random grab bag of interesting things.\u201d Mathematicians don\u2019t treat it that way. They think it\u2019s an ordered structured space that they are exploring. They think they\u2019re, especially Platonist mathematicians think they are discovering, they\u2019re not inventing. You don\u2019t have a choice. You start with set theory, eventually you find out the value of E. You didn\u2019t have a choice about that. That\u2019s what you found out. You discovered that.<\/p>\n<p>So I think more optimistically that this is not a random grab bag of stuff. This is some kind of structured space of patterns, mathematical patterns.<\/p>\n<p>Now you can take one other step and you say, \u201cInteresting. How do we know that these patterns are only of relevance to math? Is it possible? Well, we know they\u2019re of relevance to physics because they constrain how physics go. What about biology? Well, biology is interesting.\u201d Imagine that there\u2019s some planet and on this planet, the highest fitness belongs to a triangle of a very specific shape. So here comes evolution and it cranks a bunch of generations and it finds the first angle. Cool. And it cranks a bunch more generations, finds the second angle. Does it need to do it again to find the third angle? Why no? Because once you know two angles of the triangle, you know the third one. Why did evolution just get to save one third of the time that it would take to figure this out? Well, you get a free gift from mathematics.<\/p>\n<p>And so I think that physics is what we call things that are constrained by these patterns. Biology are the things that are enabled or facilitated by these patterns. I think biology uses the hell out of these things and we\u2019ll talk about what they are momentarily. But now you say, \u201cOkay, so they\u2019re relevant in physics, they\u2019re relevant in biology, what kinds of patterns are there?\u201d Well, there are passive things, like the value of E and some fractals and things like that. But could it be that there are other patterns in this space that look a lot like things that are not studied by mathematicians? Maybe they look a lot like things that are studied by behavioral scientists. Could they be patterns that have some capacity for memory or patterns that have capacity for problem solving? Could they be recognizable as kinds of minds?<\/p>\n<p>And so maybe, and so this is the kind of crazy claim that I\u2019m making, maybe the relationship between the mind and the body is exactly the same relationship as between the truths of mathematics and physics. So this is an old idea. Descartes, for example, in the West is associated with this that, okay, the mind is this non-material thing somewhere. And then of course immediately the princes of Bohemia and other people immediately nailed him on this idea, but how does the interaction happen? How do you have a non-physical pattern making the brain sort of dance like a puppet? Energy conservation laws, how could that possibly work? And I don\u2019t think he said this, and I don\u2019t know why he didn\u2019t say this because he was a mathematician. He could have said, I think, \u201cYou already have this problem. Since the time of Pythagoras you have this problem that you have these immaterial truths of mathematics are constraining the physics of our universe. We already have this interaction.\u201d This is not new. This has been around for forever. This is a kind of interaction where some of these truths that come from a different space of facts absolutely constrain and enable things that happen in the physical world.<\/p>\n<p>So one thing you might think about is whether some of these patterns, and we have right now, if anybody\u2019s interested, I give you a link to it, we\u2019re having this thing I organized called the Symposium on the Platonic Space. And we\u2019ve got about 26 people. I initially thought it was going to be three people, me and these two other groups, it turned out there\u2019s like 26 people who gave awesome talks about this stuff talking about this notion, I think it\u2019s going to be huge. And I think it has all kinds of very practical implications because what do you get? Well, maybe you get static patterns, but maybe you get dynamic patterns that are more like behavioral policies or even competencies, but maybe you also get compute.<\/p>\n<p>And if you get compute, and we can talk about this because we\u2019ve actually done some experiments on this, if you actually get compute this way, maybe the way we\u2019ve been totally adding up the cost of computation isn\u2019t right because we\u2019ve been looking at the front end. And I actually think this is what\u2019s happening here, is that the theories of computation that we have are mostly about the front end interface, and they\u2019ve kind of been neglecting some stuff that happens on the backend. And we\u2019ve just begun, we published a couple of things on it. There\u2019s lots more coming. So I think that\u2019s an exciting new area that may have all kinds of implications for cognition and behavioral science more generally.<\/p>\n<p><strong>Tim Ferriss: <\/strong>All right. So people will definitely be interested in the Symposium on the Platonic Space, so we\u2019ll include links to that for sure.<\/p>\n<p>Separately, lots of things I want to ask you offline that relate to this. But I will say just a confession briefly, which is one of my biggest regrets is that in 10th grade I and my brother had very different experiences with math. I was very good at math up to that point. My brother also, he had a great math teacher in 10th grade. I had a really, let\u2019s call her abusive teacher in 10th grade. I at that point retired from mathematics. My brother went on to get a PhD in statistics and has done computer science and data science. And it\u2019s to this day one of my biggest regrets that I stopped. It\u2019s wild to have these inflection points. Same school, two different teachers.<\/p>\n<p><strong>Michael Levin: <\/strong>Wow. Amazing.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. So, never too late, I guess, to go pick up a textbook. I wanted to ask you to expand on the compute piece that you alluded to at the end. Could you say more about that?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. There are two pieces to this that people should know about. One is this idea called polycomputing. And this is something that Josh Bongard and I, and his student who\u2019s now a postdoc in my group, Atoosa Parsa, has taken on. And it\u2019s this idea that when there\u2019s a physical event, something is physically happening. It might be current going through a logic gate in your computer, or it might be something else like that. The question of what is it actually computing is in the eye of the beholder. So, multiple observers could be looking at the same exact physical thing going on and seeing different things being computed, okay?<\/p>\n<p>And I can go into details, but I\u2019ll give you a very simple example of this. And this was a paper that my group put out about a year and a half ago. There are these things called sorting algorithms. And these are very simple sets of rules. They\u2019re usually about six lines of code, something like that, that are designed to \u2014 they\u2019re recipes that you follow. It\u2019s an algorithm, so you follow the steps. And the idea is you\u2019re handed a list of numbers, and these numbers are all jumbled up. They\u2019re out of order randomly. And the algorithm is designed to sort them so that everything is sorted. You might think of the way \u2014 if somebody gives you a bunch of names and you need to do a phone book, you want to put them alphabetical like that, or numbers, that kind of thing. These sorting algorithms, they have a couple of features. One feature is that they\u2019re short, they\u2019re fully deterministic, meaning that there\u2019s no randomness, there\u2019s no question about what to do. You just follow step by step, that\u2019s it. And people have been studying them for about 80 years.<\/p>\n<p>Every computer science 101 student has had to deal with these sorting algorithms. Okay. So, what we showed, long story short, is that if you actually watch what they\u2019re doing, yeah, they\u2019re sorting numbers, but if you watch carefully, and apparently nobody has actually looked, and I think this goes back to the thing I said earlier. If you\u2019re completely convinced that these things are dumb machines that only do what you ask them to do, why would you look, and at what else they\u2019re doing while they\u2019re sorting? And that\u2019s exactly this kind of thing where the paradigm that you\u2019re using or the formalism that you\u2019re using constrains what experiments you do or what you can see, right? Like this matters.<\/p>\n<p>So, if you\u2019re not so sure, as I wasn\u2019t, that these things are only doing what you asked them to do, what you find is two general classes of things. One is that the way they do them has extra behavioral competencies, things like delay gratification, things that a behavioral scientist would recognize, that you never coded in the algorithm. You know, because it\u2019s not some big, hairy, like three billion parameter neural net or whatever, it\u2019s six lines of code. You can see all the code. You know what is there. Unlike biology, there\u2019s no new mechanisms to be discovered. There it is. It\u2019s all there. That\u2019s why I picked this for the shock value of exactly that, that no one could say that, \u201cWell, there\u2019s probably some mechanism that you just haven\u2019t found yet.\u201d So, that\u2019s the first thing.<\/p>\n<p>And the second thing is that while they are sorting the numbers, which of course they do, they are also doing some other stuff that again, you never asked them to do. And these other things, I\u2019ve called them side quests. They\u2019re like these little side quests. You can also call them intrinsic motivations, because like with any system, like with a kid in school, as you were saying, there\u2019s things you force them to do. And then within that, within the space in between that, the time they have or whatever, you get to find out what they really want to do, right? If you don\u2019t overdo it, if you give them a little bit of room, you find out that, but what is the intrinsic, what is their sort of inner nature or their \u2014 you get the idea, that kind of thing.<\/p>\n<p>So, basically what we found is that there is a simple, minimal version of that even in the most dumbest, fully deterministic \u2014 this is nothing about determinism or randomness or indeterminism. This is the idea that our view of what an algorithm is and how much of what the thing is doing it captures is incomplete.<\/p>\n<p>It captures very well the thing you asked it to do, but it does not provide a good view of, but what else does it want to do? And apparently, in a very minimal way, even extremely simple systems have this. Andrea Morris wrote a really good story for Forbes about all of this. It\u2019s like, I think very generally understandable. And, on my blog, I have a couple of pieces about trying to explain this in a very simple way.<\/p>\n<p>The bottom line is this. One observer likes the sorting, and you pay for the steps of the algorithm. Of course, every step you do, you pay for it, so you pay for the sorting. But all the other stuff it\u2019s doing, that\u2019s all free, because there are no extra steps. You didn\u2019t have to do the other steps. It does it while it\u2019s doing the other thing. So, if you had a different observer that\u2019s interested in the other thing, they got it for free. And so now the question is, how much of that. These, I call them ing\u2026\u2014well, this is a word that exists\u2014ingressions into the physical world of some of these patterns, like how many of them actually are there? And how much extra oomph do you get when you don\u2019t know that you got it? And in some cases that might be great, because that might be facilitating things you want to do.<\/p>\n<p>In other cases, you might have a machine that has this going on where you don\u2019t want that happening. You\u2019d rather that not be happening. And we have a very active research program right now trying to figure out basically better ways to detect it, better ways to facilitate it, and ways to suppress it, because there will be situations where you don\u2019t want this thing doing other stuff.<\/p>\n<p>And so, that\u2019s the question, what are we getting? Are we getting free compute here? Are we getting something else? I\u2019m not even sure we have the vocabulary for it yet, because that\u2019s just not been the way people have thought about these things.<\/p>\n<p><strong>Tim Ferriss: <\/strong>So, to dig a bit deeper on that, as you develop the vocabulary, the better understanding of how to measure, understand, inhibit, or facilitate this type of off-gassing isn\u2019t the right term, but sort of like \u2014\u00a0<\/p>\n<p><strong>Michael Levin: <\/strong>That\u2019s cool.<\/p>\n<p><strong>Tim Ferriss: <\/strong>\u2014 secondary activities. Well, I\u2019m thinking of this technology, I think it\u2019s called [Remora], which is this device, the hardware device they throw on long haul trailers and so on to basically take the exhaust and convert it into something useful. It\u2019s not the best metaphor for what you\u2019re mentioning. But as that, as we flash forward five years or however long it is, I mean, compute is a very pressing problem, right? So there are tremendous incentives. If there were a pot of gold at the end of the rainbow, so to speak, with this, if it were even five percent possible that the Metas of the world and so on would need fewer fission, let alone fusion reactors to produce the power they need, then this is of great commercial interest, right?<\/p>\n<p><strong>Michael Levin: <\/strong>Correct.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Intellectual, certainly. But what might, and I know I\u2019m asking for some real speculative leaps here probably at this point, but what might that look like in the future for compute within, just for the time being, compute within the context of hyperscalers who are like, \u201cOkay, we need 20X the capacity of the current power grid or whatever to do what we want to do.\u201d<\/p>\n<p><strong>Michael Levin:<\/strong> A couple of things. So first, this is very late breaking stuff, so take everything I say here with a grain of salt, right? We\u2019ll see how it shakes out. But I think you\u2019re right. I think this is going to have massive implications. Oh, and first of all, the off-gassing actually thing is important, because one thing about that metaphor, the Lamprey metaphor, is that there is a main thing that it\u2019s doing, and then there are these side effects. But what\u2019s interesting about polycomputing is that you actually don\u2019t know which is the main thing. So I look at this and I say, \u201cIt\u2019s a sorting algorithm, and oh my God, it does this other thing we call clustering.\u201d Aliens come down, they look at it and they go, \u201cWell, that\u2019s a cool clustering algorithm. Wait, it sorts too? Holy crap.\u201d<\/p>\n<p>So, it\u2019s important that it\u2019s not obvious at all, which is the main thing. Okay. So, let\u2019s just say we have a set of things that it does. There\u2019s two possibilities how it could come out. I think one possibility is that multiple of these are useful as they are. And people can sort of siphon off actionable information, valuable utility out of them how they are. We\u2019re certainly investigating that, how to do that. That\u2019s one possibility.<\/p>\n<p>Another possibility is that there is the thing you forced it to do, but there\u2019s also a bunch of other stuff, which is much more whatever it \u201cwants to do.\u201d And that stuff may not actually be what you ever wanted or needed. In other words, there is no guarantee, right? So, you have a student and you\u2019re making them study math or whatever, something useful, accounting, like you got to get a job or whatever. And then while in my spare time I make, I don\u2019t know, figurines or something. And there is no guarantee that this other thing is ever going to be commercially valuable.<\/p>\n<p>It might be really important in understanding the true nature of what you have, but there\u2019s no saying that whatever it actually wants we would find commercially valuable, right? I don\u2019t think you can guarantee that. I think it\u2019s going to be a combination of both of these things, but this latter thing has an implication for AI. And the implication is this, that when we are looking at a language model, for example, and people are debating, \u201cIs it this, is it that? I asked it how it was feeling and it told me that it had an inner world and all of this.\u201d Okay. But what we don\u2019t know is whether the talking, right, the language use is at all related to what the actual intelligence is in this thing. Maybe, but I\u2019ll just say that in our sorting algorithm the additional thing it\u2019s doing is not sorting, it\u2019s something else.<\/p>\n<p>So, it\u2019s entirely possible that in these AIs, the thing we have forced them to do, which is to talk, and the thing that we\u2019re all obsessed about or the things it says could be a complete red herring as far as what kind of intelligence is actually there, what does it want? How do we communicate with it? The verbal interface that we\u2019re all sort of so glued in on might not be the interesting part of that equation. And so, that\u2019s my only thing is that some of this may very well be commercially viable, but some of it may have implications that are very different, that are not about the utility of the compute, but about teaching you about what do you really have when you have a system like that. And I think that\u2019s where a lot of surprises are coming.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah. Folks can go back and watch <em>Ex Machina<\/em>, but I do want to ask you about sci-fi in a moment and your most recommended sort of sci-fi books or films, favorites. But before we get there, this is me just ruminating, and I\u2019m going to apologize in advance for anthropomorphizing. But thinking about the school child example, studying math or accounting and making the figurines, I wonder if the \u201cunproductive side activities\u201d in some cases might prove to be really critical to the forced function in the sense that that student who\u2019s studying math needs to let off some steam and do something different in order to have the endurance and periods of focus to actually do the mathematics. So, if you split the baby and get rid of the figurine, do you accidentally handicap the main function at the same time? I don\u2019t know.<\/p>\n<p><strong>Michael Levin: <\/strong>That\u2019s a great question. And that is exactly what we are studying right now. I have people working on this exact question. And specifically, what is the relationship among the different things that are happening here? Are they living in completely parallel universes such that they don\u2019t really touch each other, or are they entangled in a way that when you mess with one you\u2019re going to have implications somewhere else? We don\u2019t know. That\u2019s a great question. I don\u2019t know the answer to that yet.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I\u2019m tempted to chew on that word \u201centangled\u201d with you, but that\u2019s probably another two-hour conversation. Sci-fi. I mean, sci-fi, as I believe you do, I just think it\u2019s so powerful in so many ways. Do you have any books, movies, anything at all, essays that are just favorites of yours or that you recommend to students or friends?<\/p>\n<p><strong>Michael Levin: <\/strong>Let\u2019s see. Okay. Well, I grew up on all classic sci-fi from the \u201950s, \u201960s, \u201970s, that kind of stuff, so all the favorites. One particular author that I love is Lem, Stanis\u0142aw Lem, L-E-M.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Oh, I\u2019ve never read Lem.<\/p>\n<p><strong>Michael Levin: <\/strong>Oh, he\u2019s amazing. So, <em>Solaris<\/em> was his, but also he has a ton of very humorous short stories, like really funny stuff. So, I like him a lot. He\u2019s a master of the absurd and kind of releasing the assumptions that we all have in ways that kind of illustrate how narrow thinking and things like that is just beautiful. I\u2019ll give you two stories that I, short stories that I like. One is<em> They\u2019re Made Out of Meat<\/em> by Terry Bisson.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Yeah, that\u2019s a great one. Very fast read for people.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. Yeah. Very fast read. It\u2019s like a page and it just reminds us all how silly some of our preconceptions are. There\u2019s another one I like, which I\u2019m going to butcher it, because I use this example, but I\u2019m sure I\u2019ve added on things that weren\u2019t really there. I think that it\u2019s <em>The Fires Within<\/em> by Clarke. And the version that I have in my head, which probably isn\u2019t really close, is the following, but I think it\u2019s valuable. Imagine there\u2019s some creatures that live in the core of the earth and they come out to the surface, so they\u2019re incredibly dense. They\u2019re hot, they\u2019re incredibly dense. They use gamma rays for vision, whatever. They come up to the surface, what do they see? Well, everything that we see here that\u2019s solid is like a thin gas to them. This isn\u2019t solid to them. They\u2019re walking through. It\u2019s like walking through a garden of smells that you like, you walk right through, disturb everything, you don\u2019t even know what\u2019s there.<\/p>\n<p>And one of them is the scientist and he says, \u201cYou know, there\u2019s like this thin plasma around the surface of our planet.\u201d And they go, \u201cOh, yeah.\u201d And he says, \u201cYeah, and it\u2019s got little patterns in it. And I\u2019ve been watching these patterns with my instruments, and these patterns, they almost look agential. They almost look like they\u2019re doing things, right? They almost look like they have little lives. They move around.\u201d And, \u201cWell, how long do these patterns stick together?\u201d \u201cWell, about 100 years.\u201d \u201cWow, that\u2019s stupid.\u201d And \u201cNothing interesting can happen like that.\u201d And I have a story on my blog based around this. He says, \u201cWe are real beings. We are real agents where physical agents, patterns in the gas can\u2019t be anything.<\/p>\n<p>So, you get the idea. The point is that even the distinction between an agent and the patterns within their cognitive system, thoughts versus thinkers, as William James said, and what\u2019s data and what\u2019s the machine like, all of this to me is a continuum, a very observer dependent continuum, and you can get there with a science fiction story.<\/p>\n<p><strong>Tim Ferriss: <\/strong>What fun. You mentioned the blog a few times. You\u2019ve got some great stuff on the blog. I\u2019ve shared some of your writing in my newsletter before, specifically your advice to students, which has some fantastic advice in it. And for folks who are listening, even if you are not in the world of science and academia, there\u2019s a lot in that piece that they can recommend it. But where would you suggest people start? If they\u2019ve enjoyed this conversation, within the landscape of your blog, are there one to three articles you might suggest they start with?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. I have a starter pack article and things like that. I can provide some links, for sure. Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Great. Okay, we\u2019ll put those in the show notes, folks, as per usual. We\u2019re going to land the plane, because I know you\u2019ve got another engagement coming up, but I\u2019ll tell you what, I\u2019m going to make it dealer\u2019s choice, but in this case you\u2019re the dealer. So, you can pick which question you want to tackle, and then we\u2019ll wind up.<\/p>\n<p><strong>Michael Levin: <\/strong>Sure.<\/p>\n<p><strong>Tim Ferriss: <\/strong>But super curious what you picked up from the late Daniel Dennett. I have a bunch of his books, really fascinating guy. Option number two is, this is a quote from the <em>New Yorker<\/em> piece in 2021, but this is a congratulatory toast from Clifford Tabin, if I\u2019m pronouncing that correctly. \u201cYou are the most likely to crash and burn and never be heard from again. You\u2019re also the most likely to do something really fundamentally important, that no one else on earth would have done, that will really change the field.\u201d<\/p>\n<p>So, I\u2019m curious about that first part, especially \u201cmost likely to crash and burn, never be heard from again\u201d and why that hasn\u2019t happened. And I suppose last, and you can answer more than one of these too, but if you could put a giant billboard out in front of, and this is metaphorically speaking, just to get a message in front of a lot of people. In front of departments of biology, or just even more broadly for lots of people to see and understand what that might be. So, I\u2019ll leave it to you to pick how you want to choose.<\/p>\n<p><strong>Michael Levin: <\/strong>Wow. Yeah. That last one, it\u2019s hard, because if there\u2019s just one billboard, I don\u2019t know. There\u2019s a lot to choose from. I\u2019ll say \u2014\u00a0<\/p>\n<p><strong>Tim Ferriss: <\/strong>You can have more than one if you want.<\/p>\n<p><strong>Michael Levin: <\/strong>Well, yeah. I mean, that\u2019s basically the blog and the website and everything, but I\u2019ll say just a couple of things about the first two, I guess. Dan was an amazing person. We agreed on a lot. We disagreed on a lot of stuff. I think he was always an incredibly generous thinker. One of the great things that he always insisted on was steel manning. And this is the idea that if you\u2019re going to shoot down somebody\u2019s viewpoint or disagree with it, you first need to articulate the absolute strongest version of it that you can.<\/p>\n<p><strong>Tim Ferriss: <\/strong>And for people who don\u2019t have context, I suppose we should just establish who Dan Dennett was. Just how would you describe him in brief? Philosopher, cognitive scientists?<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Understatement.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. He passed away, I think, in the last year. And before that, I think he was widely written about as maybe one of the most important living philosophers today. I think I\u2019ve seen that. And yeah, he was a professor at Tufts where I am, and he was just an incredible thinker and he wrote many interesting and popular books and so on. Yeah. So, it\u2019s the opposite of straw man, this idea that there\u2019s no point critiquing a bad argument. You should be critiquing the best possible version of an argument that you can. And so, I think that\u2019s extremely valuable, is to take the view and understand it so thoroughly that you can give it a really strong defense. And then if you want, go back and shoot it down after that. But first you got to do the first part. So, I thought that was really, really, really important.<\/p>\n<p>And I guess the second part, so Cliff Tabin is a great scientist. He\u2019s a geneticist. He was my PhD mentor. I did my PhD with him at Harvard. And yeah, I mean, I don\u2019t know. I\u2019m getting old now, getting into retirement. At some point we got to call it which way it\u2019s going to be. I don\u2019t remember how long ago it was that he said it, but it could still happen. It could still crash and burn, I suppose. Why not?<\/p>\n<p><strong>Tim Ferriss: <\/strong>Did he say that just because of an intrinsic intensity that you have? What would lead him to say something like that?<\/p>\n<p><strong>Michael Levin: <\/strong>I don\u2019t want to put words in his mouth, but what I hear him saying is that. I mean, I\u2019m very strategic in what I say when, but I don\u2019t really have a filter on what I think.<\/p>\n<p><strong>Tim Ferriss: <\/strong>No halfway measures.<\/p>\n<p><strong>Michael Levin: <\/strong>Yeah. I\u2019m just not very constrained as far as what I\u2019m willing to think and eventually say if I think there\u2019s good reason to say it. And I think that\u2019s what he was talking about. That\u2019s a very dangerous thing, because let\u2019s face it, in science most of what we say is wrong. And I\u2019m clear on that with people all the time. I\u2019ll say what I think now, and I\u2019ll say it as strongly as I possibly can, but I\u2019m under no illusions that we have the right answer to any of these extremely difficult questions. So, most of it is probably wrong in some important way. And I think he was just commenting on the fact that I say a lot of things that are counter paradigm and not in agreement with what the mainstream thinks. Occasionally that goes well, usually that goes very poorly, which is what I think he was pointing at.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Mike, thank you so much for the time.<\/p>\n<p><strong>Michael Levin: <\/strong>Thank you so much.<\/p>\n<p><strong>Tim Ferriss: <\/strong>I\u2019ve had so much fun in this conversation. I want to make sure we point people to the right places. I\u2019ve got a few websites in front of me here, thoughtforms.life, that\u2019s one. We\u2019ve got Dr, D-R, michaellevin.org as well. Are there any other websites or profiles you\u2019d like to point to? Are you active on X or any other platforms?<\/p>\n<p><strong>Michael Levin: <\/strong>I have, yeah, @drmichaellevin on X. Yeah. The thoughtforms.life is the blog. That\u2019s my personal blog. So, I say things there that I wouldn\u2019t put on the website, which is my official lab website. And you can sign up for updates on the book and all that kind of stuff. The drmichaellevin.org is the official lab website. So, that has all of our papers, all of the software, you can download the data. So, that\u2019s like all the stuff to back up all these crazy things that I\u2019m saying. All of that is on drmichaellevin.org. There are also lists of books that I recommend to my students and things like that.<\/p>\n<p>There is a YouTube channel, which also has some conversations. I\u2019ve b<\/p>\n<p>een for the last, I don\u2019t know, five or six years I\u2019ve been hitting record on some meetings I\u2019ve had with some amazing people. So, some really interesting collaborators, and all of that is there for you to sort of be a fly on the wall. So, that\u2019s fun too.<\/p>\n<p><strong>Tim Ferriss: <\/strong>And the YouTube channel is linked to from thoughtforms.life?<\/p>\n<p><strong>Michael Levin: <\/strong>Probably. I\u2019ll send you the link. I don\u2019t even know if I remember what exactly the URL is, so I\u2019ll send you the link.<\/p>\n<p><strong>Tim Ferriss: <\/strong>Mike, thank you so much. I hope this is not our last conversation.<\/p>\n<p><strong>Michael Levin: <\/strong>Absolutely.<\/p>\n<p><strong>Tim Ferriss: <\/strong>And for people listening or watching, we will link to lots of things, everything that we can possibly link to from this conversation and more at tim.blog\/podcast as per usual, just search Michael Levin or probably Levin. I think you might be the only Levin, L-E-V-I-N, and it will pop right up. So, you\u2019ll have plenty of resources to do more digging and more thinking, more assumption testing, assumption bending in a lot of ways. And until next time, as always, be a bit kinder than is necessary to others, but also to yourself.
