Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | the better locus of control is not always at the lowest level. This is why we don't all program | https://karpathy.ai/lexicap/0325-large.html#01:05:13.600 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | with a soldering iron. We take advantage of the high level intelligences that are there, | https://karpathy.ai/lexicap/0325-large.html#01:05:18.480 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | intelligences that are there, which means trying to figure out, okay, which of your tissues can | https://karpathy.ai/lexicap/0325-large.html#01:05:24.720 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | learn? What can they learn? Why is it that certain drugs stop working after you take them for a while | https://karpathy.ai/lexicap/0325-large.html#01:05:28.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | with this habituation, right? And so can we understand habituation, sensitization, associative | https://karpathy.ai/lexicap/0325-large.html#01:05:35.200 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | learning, these kinds of things in chemical pathways? We're going to have a completely | https://karpathy.ai/lexicap/0325-large.html#01:05:40.160 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | different way. I think we're going to have a completely different way of using drugs and of | https://karpathy.ai/lexicap/0325-large.html#01:05:44.400 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | medicine in general when we start focusing on the goal states and on the intelligence of our | https://karpathy.ai/lexicap/0325-large.html#01:05:49.200 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | subsystems as opposed to treating everything as if the only path was micromanagement from | https://karpathy.ai/lexicap/0325-large.html#01:05:54.560 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | chemistry upwards. Well, can you speak to this idea of somatic psychiatry? What are somatic cells? | https://karpathy.ai/lexicap/0325-large.html#01:05:59.040 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | How do they form networks that use bioelectricity to have memory and all those kinds of things? | https://karpathy.ai/lexicap/0325-large.html#01:06:05.200 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Yeah. What are somatic cells like basics here? Somatic cells just means the cells of your body. | https://karpathy.ai/lexicap/0325-large.html#01:06:11.760 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Soma just means body, right? So somatic cells are just the... I'm not even specifically making a | https://karpathy.ai/lexicap/0325-large.html#01:06:16.160 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | distinction between somatic cells and stem cells or anything like that. I mean, basically all the | https://karpathy.ai/lexicap/0325-large.html#01:06:20.000 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | cells in your body, not just neurons, but all the cells in your body. They form electrical | https://karpathy.ai/lexicap/0325-large.html#01:06:23.920 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | networks during embryogenesis, during regeneration. What those networks are doing | https://karpathy.ai/lexicap/0325-large.html#01:06:28.400 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | in part is processing information about what our current shape is and what the goal shape is. | https://karpathy.ai/lexicap/0325-large.html#01:06:33.280 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Now, how do I know this? Because I can give you a couple of examples. One example is when we started | https://karpathy.ai/lexicap/0325-large.html#01:06:39.600 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | studying this, we said, okay, here's a planarian. A planarian is a flatworm. It has one head and one | https://karpathy.ai/lexicap/0325-large.html#01:06:45.120 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | tail normally. And the amazing... There's several amazing things about planaria, but basically they | https://karpathy.ai/lexicap/0325-large.html#01:06:50.400 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | kind of... I think planaria hold the answer to pretty much every deep question of life. | https://karpathy.ai/lexicap/0325-large.html#01:06:55.200 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | For one thing, they're similar to our ancestors. So they have true symmetry. They have a true | https://karpathy.ai/lexicap/0325-large.html#01:07:00.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | brain. They're not like earthworms. They're a much more advanced life form. They have lots | https://karpathy.ai/lexicap/0325-large.html#01:07:04.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | of different internal organs, but they're these little... They're about maybe two centimeters in | https://karpathy.ai/lexicap/0325-large.html#01:07:08.320 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | the centimeter to two in size. They have a head and a tail. And the first thing is planaria are | https://karpathy.ai/lexicap/0325-large.html#01:07:12.240 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | immortal. So they do not age. There's no such thing as an old planarian. So that right there | https://karpathy.ai/lexicap/0325-large.html#01:07:17.680 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | tells you that these theories of thermodynamic limitations on lifespan are wrong. It's not that | https://karpathy.ai/lexicap/0325-large.html#01:07:22.320 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | well over time everything degrades. No, planaria can keep it going for probably how long have | https://karpathy.ai/lexicap/0325-large.html#01:07:27.680 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | they been around 400 million years. So the planaria in our lab are actually in physical | https://karpathy.ai/lexicap/0325-large.html#01:07:33.280 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | continuity with planaria that were here 400 million years ago. So there's planaria that | https://karpathy.ai/lexicap/0325-large.html#01:07:38.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | have lived that long essentially. What does it mean physical continuity? Because what they do | https://karpathy.ai/lexicap/0325-large.html#01:07:43.600 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | is they split in half. The way they reproduce is they split in half. So the planaria, the back end | https://karpathy.ai/lexicap/0325-large.html#01:07:49.280 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | grabs the petri dish, the front end takes off and they rip themselves in half. But isn't it some | https://karpathy.ai/lexicap/0325-large.html#01:07:54.560 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | sense where like you are a physical continuation? Yes, except that we go through a bottleneck of one | https://karpathy.ai/lexicap/0325-large.html#01:07:59.680 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | cell, which is the egg. They do not. I mean, they can. There's certain planaria. Got it. So we go | https://karpathy.ai/lexicap/0325-large.html#01:08:07.600 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | through a very ruthless compression process and they don't. Yes. Like an auto encoder, you know, | https://karpathy.ai/lexicap/0325-large.html#01:08:11.760 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | sort of squashed down to one cell and then back out. These guys just tear themselves in half. | https://karpathy.ai/lexicap/0325-large.html#01:08:17.200 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | And so the other amazing thing about them is they regenerate. So you can cut them into pieces. | https://karpathy.ai/lexicap/0325-large.html#01:08:22.880 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | The record is, I think, 276 or something like that by Thomas Hunt Morgan. And each piece regrows a | https://karpathy.ai/lexicap/0325-large.html#01:08:26.640 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | perfect little worm. They know exactly, every piece knows exactly what's missing, what needs | https://karpathy.ai/lexicap/0325-large.html#01:08:32.560 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | to happen. In fact, if you chop it in half, as it grows the other half, the original tissue shrinks | https://karpathy.ai/lexicap/0325-large.html#01:08:36.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | so that when the new tiny head shows up, they're proportional. So it keeps perfect proportion. | https://karpathy.ai/lexicap/0325-large.html#01:08:45.360 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | If you starve them, they shrink. If you feed them again, they expand. Their control, | https://karpathy.ai/lexicap/0325-large.html#01:08:50.080 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | their anatomical control is just insane. Somebody cut them into over 200 pieces. | https://karpathy.ai/lexicap/0325-large.html#01:08:54.160 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Yeah. Thomas Hunt Morgan did. Hashtag science. Amazing. And maybe more. I mean, | https://karpathy.ai/lexicap/0325-large.html#01:08:58.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | they didn't have antibiotics back then. I bet he lost some due to infection. I bet it's | https://karpathy.ai/lexicap/0325-large.html#01:09:03.520 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | actually more than that. I bet you could do more than that. Humans can't do that. | https://karpathy.ai/lexicap/0325-large.html#01:09:06.720 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Well, yes. I mean, again, true, except that... Maybe you can at the embryonic level. | https://karpathy.ai/lexicap/0325-large.html#01:09:11.760 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Well, that's the thing, right? So when I talk about this, I say, just remember that | https://karpathy.ai/lexicap/0325-large.html#01:09:16.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | as amazing as it is to grow a whole planarian from a tiny fragment, | https://karpathy.ai/lexicap/0325-large.html#01:09:21.120 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | half of the human population can grow a full body from one cell. So development is really, | https://karpathy.ai/lexicap/0325-large.html#01:09:24.880 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | you can look at development as just an example of regeneration. | https://karpathy.ai/lexicap/0325-large.html#01:09:30.640 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Yeah. To think, we'll talk about regenerative medicine, but there's some sense of what would | https://karpathy.ai/lexicap/0325-large.html#01:09:34.240 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | be like that warm in like 500 years where I can just go regrow a hand. | https://karpathy.ai/lexicap/0325-large.html#01:09:39.600 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Yep. With given time, it takes time to grow large things. | https://karpathy.ai/lexicap/0325-large.html#01:09:46.320 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | For now. | https://karpathy.ai/lexicap/0325-large.html#01:09:49.920 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Yeah, I think so. I think. | https://karpathy.ai/lexicap/0325-large.html#01:09:50.560 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | You can probably... Why not accelerate? Oh, biology takes its time? | https://karpathy.ai/lexicap/0325-large.html#01:09:51.840 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | I'm not going to say anything is impossible, but I don't know of a way to accelerate these | https://karpathy.ai/lexicap/0325-large.html#01:09:56.800 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | processes. I think it's possible. I think we are going to be regenerative, but I don't know of a | https://karpathy.ai/lexicap/0325-large.html#01:10:00.080 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | way to make it faster. | https://karpathy.ai/lexicap/0325-large.html#01:10:04.000 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | I could just think people from a few centuries from now would be like, well, they used to have | https://karpathy.ai/lexicap/0325-large.html#01:10:04.800 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | to wait a week for the hand to regrow. It's like when the microwave was invented. You can toast | https://karpathy.ai/lexicap/0325-large.html#01:10:10.080 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | your... What's that called when you put a cheese on a toast? It's delicious is all I know. I'm | https://karpathy.ai/lexicap/0325-large.html#01:10:17.920 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | blanking. Anywho. All right. So planaria, why were we talking about the magical planaria that they | https://karpathy.ai/lexicap/0325-large.html#01:10:27.360 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | have the mystery of life? | https://karpathy.ai/lexicap/0325-large.html#01:10:33.280 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Yeah. So the reason we're talking about planaria is not only are they immortal, | https://karpathy.ai/lexicap/0325-large.html#01:10:34.320 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | not only do they regenerate every part of the body, they generally don't get cancer, | https://karpathy.ai/lexicap/0325-large.html#01:10:37.680 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | which we can talk about why that's important. They're smart. They can learn things. You can | https://karpathy.ai/lexicap/0325-large.html#01:10:43.920 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | train them. And it turns out that if you train a planaria and then cut their heads off, the tail | https://karpathy.ai/lexicap/0325-large.html#01:10:47.360 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | will regenerate a brand new brain that still remembers the original information. | https://karpathy.ai/lexicap/0325-large.html#01:10:52.320 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Do they have a biological network going on or no? | https://karpathy.ai/lexicap/0325-large.html#01:10:56.000 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Yes. | https://karpathy.ai/lexicap/0325-large.html#01:10:58.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | So their somatic cells are forming a network. And that's what you mean by a true brain? What's the | https://karpathy.ai/lexicap/0325-large.html#01:10:59.280 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | requirement for a true brain? | https://karpathy.ai/lexicap/0325-large.html#01:11:05.200 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Like everything else, it's a continuum, but a true brain has certain characteristics as far as the | https://karpathy.ai/lexicap/0325-large.html#01:11:07.200 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | density, like a localized density of neurons that guides behavior. | https://karpathy.ai/lexicap/0325-large.html#01:11:12.080 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | In the head. | https://karpathy.ai/lexicap/0325-large.html#01:11:15.680 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | Exactly. Exactly. If you cut their head off, the tail doesn't do anything. It just sits there | https://karpathy.ai/lexicap/0325-large.html#01:11:16.240 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | until a new brain regenerates. They have all the same neurotransmitters that you and I have. | https://karpathy.ai/lexicap/0325-large.html#01:11:22.080 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | But here's why we're talking about them in this context. So here's your planaria. You cut off the | https://karpathy.ai/lexicap/0325-large.html#01:11:28.000 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | head. You cut off the tail. You have a middle fragment. That middle fragment has to make one | https://karpathy.ai/lexicap/0325-large.html#01:11:32.720 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | head and one tail. How does it know how many of each to make? And where do they go? How come it | https://karpathy.ai/lexicap/0325-large.html#01:11:35.840 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | doesn't switch? How come, right? So we did a very simple thing. And we said, okay, let's make the | https://karpathy.ai/lexicap/0325-large.html#01:11:40.080 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | hypothesis that there's a somatic electrical network that remembers the correct pattern, | https://karpathy.ai/lexicap/0325-large.html#01:11:46.960 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | and that what it's doing is recalling that memory and building to that pattern. | https://karpathy.ai/lexicap/0325-large.html#01:11:52.400 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | So what we did was we used a way to visualize electrical activity in these cells, right? It's a | https://karpathy.ai/lexicap/0325-large.html#01:11:55.760 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | variant of what people used to look for electricity in the brain. And we saw that that fragment has a | https://karpathy.ai/lexicap/0325-large.html#01:12:01.920 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | very particular electrical pattern. You can literally see it once we developed the technique. | https://karpathy.ai/lexicap/0325-large.html#01:12:08.080 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | It has a very particular electrical pattern that shows you where the head and the tail goes, | https://karpathy.ai/lexicap/0325-large.html#01:12:12.720 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | right? You can just see it. And then we said, okay, well now let's test the idea that that's | https://karpathy.ai/lexicap/0325-large.html#01:12:17.920 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | a memory that actually controls where the head and the tail goes. Let's change that pattern. So | https://karpathy.ai/lexicap/0325-large.html#01:12:22.240 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | basically, incept the false memory. And so what you can do is you can do that in many different | https://karpathy.ai/lexicap/0325-large.html#01:12:25.920 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | ways. One way is with drugs that target ion channels to say, and so you pick these drugs | https://karpathy.ai/lexicap/0325-large.html#01:12:29.680 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | and you say, okay, I'm going to do it so that instead of this one head, one tail electrical | https://karpathy.ai/lexicap/0325-large.html#01:12:34.640 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | pattern, you have a two headed pattern, right? You're just editing the electrical information | https://karpathy.ai/lexicap/0325-large.html#01:12:39.600 |
Michael Levin: Biology, Life, Aliens, Evolution, Embryogenesis & Xenobots | Lex Fridman Podcast #325 | in the network. When you do that, guess what the cells build? They build a two headed worm. | https://karpathy.ai/lexicap/0325-large.html#01:12:43.440 |
