I love the attitude that Lee brings to scientific inquiry. "Here's an idea. I know I'm wrong; but how am I wrong, and how wrong am I?" The guy genuinely cares about advancing the conversation and creating opportunities for the next person to build on his ideas. It's cool to see.

one of my favorite quotes from a scientist ever is Lee Cronin on Lex: "I'm not really qualified to answer this but i'll have a go" which is just a perfect scene of what science is, or what it should be.

Its amazing to me how throughout this he openly admits to making things up as he goes along, or as he's talking he'll stop and say "oh! here's an idea that might build upon this topic". Its this kind of mind that is required for massive leaps in scientific understanding. So incredibly interesting to hear him speak.

[@smmoney7415]

This was the best convo with Lee so far, no doubt. The assembely theory was explained in a very informative and interesting way, while still a bit complicated for the nerds out there. But the fact that so many people got upset about the paper, the fact that its published in nature, and that he's so emotional about it just lets you feel the power of science. Power of the discovery, of the passion in the work done, the power of the many failures, and the power of the resilience to get through it. So much emotion comes through Lee here that I didnt see in his previous times on the podcast, and this is absolutely what the lex podcast is all about. What a great convo. Plus alot of talk about free will, questions about god, AI, nucleur weapons, everything gets a little touch here. Couldnt have asked for a better 3 hours of my life.

[@Mrachsohallo]

This is a guest I didnt know we needed. Not a usual academic scientist. He is deeply curious and can explain his complex thoughts in simple langague.. Its often the other way around.

His previous one was fantastic too. This guy is legit, fun fact he is a "Regius Professor" which from wiki "are traditionally addressed as 'Regius' and not 'Professor'" which is hilarious and I love it. Royal professor like a knighted prof. We need more cool ways to address our scientists in the US, give them status over the politicians.

[@davemathews5446]

So grateful for your work Lex! At about 1:17:30 Lee said something really interesting about learning in LLMs, and I would love to hear it explored more in the future. His point was that LLMs are not currently being taught in the sequential way that humans learn, meaning not the way we teach children. They do not get taught the basic fundamentals and then build on them over time towards more complex levels of comprehension and intelligence. They just get all types of information downloaded without any time related sequence of learning in the data set. I think this is a huge flaw in trying to build something truly intelligent. Cheers!

[@beatrisbeatris9616]

Agreed

[@enangl2]

AFAIK they do use some sequential learning with LLMs. The LLM first learns to predict the next word, later it learns how to work with instructions and after that it learns proper behavior. I recall also some LLMs are later trained on specific data related to some specific topic for better answers regarding that topic.

The bravery of those scientists who push to challenge the current thinking, in any field, is an arduous process, not intended for the faint-of-heart. This is an important topic and I thank both Lee Cronin and Lex Fridman for bringing this to the public's eye. I have learned so much from this conversation and cannot wait to learn more from Cronin on assembly theory.

[@BrandonSchmit]

The problem is that it's not useful. He's just come up with a way to give names to the steps any chemist or biologist already understands. This theory is useless and doesn't lend itself to gaining insights into why a system is the way it is and whether we humans would call it "life". In order to use this classification system, you have to have full knowledge of the system already in order to create the index. Once you already know all the steps, you don't gain anything by calling those steps an index. Useless. Just because you find molecules that are complex, doesn't mean those molecules are alive. There are plenty of complex molecules that reproduce faster in a local environment that aren't alive. The purpose is to find life. You must really know a system in order to say a certain molecule is evidence of life. Lee hasn't described the threshold where lifeless becomes life. He's put the cart before the horse. Saying that any molecule above some threshold number of steps (which he doesn't currently know) is life isn't great science. You must find this threshold on earth first and then apply it elsewhere. It might be that there are plenty of highly sophisticated molecules on other planets that exist due to the local environment and abundance of precursor molecules that we wouldn't call "life" if we were actually there and looking at the system in person.

[@culpritgene]

This was an emotional rollercoaster, much more so than an average piece of fiction. I went from being very curious and enthusiastic to learn more about AT to transitioning into skepticism, to being really annoyed and honestly angry at Lee for seemingly avoiding answering direct questions and instead bombarding the audience with new eccentricities and dismissing criticism as a bunch of straw men, to questioning myself if I am so irrationally annoyed because I can see myself at his place (not really), to finding peace again and the commitment to learn more about AT even if it is not what I've anticipated, to becoming sympathetic with Lee and cautiously willing to hear more from him. Even if for the single fact that he gives a really good chance at practicing level-headedness and avoiding jumping to conclusions.

[@GrampaClan]

Wow finally someone wrote out my exact thoughts I had while listening to this. It was so annoying not answering the direct questions

[@DeriqueDeCoux]

That aspect was quite frustrating. A lot of cool new ideas to ponder but it’s just ideas with little direction. Then attacking/dismissing the criticism just pushed it over the bullshit barrier for me at some points.

[@rjd53]

It's always a pleasure to hear Leee Cronin. He is the most flexible and openminded scientist I 've seen so far online. He doesn't just propagate ready-made theories but he is continuously thinking while talking, himself creating novelty in the realm of ideas, at the same time ready to probe and test them. People like him make science interesting.

This is SO valuable to hear for those youth today who have similar minds to explore the gaps in between what we believe we can explain. No need to be embarrassed. So many would have the same emotional journey. Sometimes it’s not seeing that that can prevent discovery. Yours and Sarah’s work is wonderful and Assembly Theory, fascinating.

[@julioivansalazar9853]

Researchers from King's College London and the University of Oxford have formally demonstrated through published papers and blog posts that Assembly Theory (AT) is formally equivalent to existing work (Shannon entropy and LZ compression grammar) without proper citation, and is a weaker version of these established concepts. This raises significant concerns about AT's originality and scientific merit, and also highlights the importance of not exaggerating intended scientific work, especially if it is not original and does not explain what their authors claim to explain. Publications include a paper in npj Systems Biology and Applications: "On the salient limitations of the methods of assembly theory and their classification of molecular biosignatures". "Assembly Theory is a weak version of algorithmic complexity based on LZ compression that does not explain or quantify selection or evolution", published in the arXiv and two medium post by Dr. Hector Zenil, broadly explaining why Assembly Theory and its marketing campaign are seriously damaging the image of science as a whole.

[@buchnejf]

I disagree that Lee is a scientist that I would want to sit next in a bar, but this was rather interesting. You have to get past Lee's approach--which I found initially pompous and imprecise--to answer a question with extreme responses like "i just throw that out out the window" and "everyone just dislikes what I say." It's only after probing him with a question that brings the topic back out of the window and puts in a place in the room. Lex does an excellent job of asking Lee explain and qualify Lee's ideas. Lee seems to be the type to want to jump to shocking statements again and again and does't realize it makes it more difficult for recipients to understand his research. Be clear and talk something through before jumping to the next possible implication. It's beyond my area of expertise, but I always wonder if someone like Lee would benefit from counseling to help him better understand how he gets in the way of expressing an idea. Interesting discussion!

This resonates so well with me.. both these men are great. The part of the universe that can't fit into the universe is the "seed" just like using a pseudo random number generator. The reason why we can't predict it like deterministically is because we don't get access to the seed until after a time-step has passed. If the seed is "located" outside the universe and exposed through time, then it can be deterministic if you include the seed & universe in one system, and indeterministic if the seed not part of the universe.. I'm not sure how that's possible, but maybe that's just the nature of the universe.

There are two types of people in this world, those who can spot genius and be excited for it, and those who can spot genius and be threatened by it. I’m glad I’m on the “be excited” side when it comes to this man.

[@geometerfpv2804]

Better to do away with the concept of genius entirely...if you were on the inside when it comes to research community, you'd see it really is not split into geniuses and non-geniuses. Sometimes people get lucky and touch on a really important idea, sometimes not. Most people do at least once throughout their career, so I guess they are all "geniuses"? It's just a silly concept. Einstein was not special, he just had the idea that was needed at that time. Mostly luck. (It wasn't his idea either, it essentially never is...it's always a small variation on some information we've already taken in. The stuff doesn't come out of nowhere, which is another unhelpful myth)

[@markmnelson]

Lee called it out multiple times in this talk himself. It’s not genius, it’s stubbornness, and the sheer dogged willingness to just keep grinding on the logic of a line of inquiry in the face of tremendous opposition and even outrage. The willingness and perseverence to keep on coming back to engage yet again with reviewers and critics, each time with a testable, falsifiable theory, saying “I know it’s probably not right yet, so please just show us how and where it’s wrong” knowing that the real progress in science isn’t getting things right, but rather in consistently getting them less wrong than any other probe we have into that part of the unknown. This is why we prioritize for colleagues with the ability to grind, in our lab.

[@christoptosis364]

@@geometerfpv2804 do we get rid of the concept entirely? Or hone it so that it’s used properly? I feel like the phenomenon that the concept is tied to is a pretty important phenomenon. I wouldn’t say “he is a genius”, rather it’s more like “his utterances are genius”. Or he is a genius “at X”. Bobby Fischer is a classic example. He was a genius at chess, but basically an idiot in every other way haha. I think it’s pretty important to be able to recognize that genius (or whatever we want to call the phenomenon). And even if we did get rid of the concept, human psychology would still likely respond to the phenomenon in the same way, it seems to me.

On AGI: It sounded like Lee missed the point of the Paperclip Maximizer, which was not to show a likely scenario, but rather to illustrate an idea that an arbitrary goal becomes dangerous under certain conditions. He also appears to conflate intelligence with consciousness in his thinking about what goal-directed behavior requires.

[@HermanWillems]

But what is AGI. I mean we humans are GI. But what is GI? Just brute force biologics. Why are not more animals as smart? Well there is a correlation of animals and their front cortex neuron count. Humans have the most then the Apes. Dolphins are also in that row. But we even have almost 2x more neurons in the front cortex than the smartest animal alive. With so many neurons with each having 7000 dynamic connections.. we are just a machine that absorbs a model of the world when we are a baby and generate a personality. We are still just machines with sensory input, the neuron black box and actuators. And some pre-programmed desires. There is no magical ghost, there is no spirit.. and consciousness?? Sounds like a name we gave to something that we thing exists but maybe does not exist. Its the illusion of being alive while our brain is still a machine that has a prediction model inside based on experience and learning. Your personality is just a reflection of your experience. Our personality changes constantly by new information. We are never the same person because our brain gets new information and then neuron connections change constantly.. yes this ability slows down when we age so we can not adapt do well when we get older this also means u are getting more conservative when older. U want things around u to stay the same, as that is the model in your brain.

[@davidchung1697]

I think Lee Cronin is correct about the limitations of the current LLMs. In general, there are some functions (mathematical or otherwise) that NNs cannot learn by training the NNs with only inputs and desired outputs of the functions. This means one has to devise special software/hardware to aid the NNs - which is contrary to the concept of AGI.

[@bazstraight8797]

I recall someone describing LLMs as a lossy compression function ie analogous to jpegs. Perhaps Yann LeCun.

[@davidchung1697]

@@bazstraight8797 I think that is a great analogy.

[@geometerfpv2804]

Why is that contrary to the concept of AGI? Nobody said AGI has to *only* use LLM tech, or even only neural nets; it will probably combine a variety of methods. It needs memory, for example, and some notion of logical progression...but both of these things are already being done. We have LLMs with supplemental reasoning structures that can do math problems. They are still general because you can give them a generic problem in English, and they solve it. I don't see what the problem is here, LLM tech is just one ingredient in the progression. It doesn't have to do the task alone, and nobody is saying you HAVE to only employ neural nets to qualify as "AI". Any computer system that can respond to general queries is going to be thought of as AGI, it doesn't matter how it works.

[@davidchung1697]

​@@geometerfpv2804Implementing special purpose application NNs is (almost) equivalent to creating sophisticated interfaces between humans and current software systems. The interfaces would take a long time and a lot of man-power to build. Barring theoretical advances in NN, that is the path we are most likely on. The AGI would allow us to bypass a lot of that - since the AGI would have the ability to learn many tasks it needs/wants on its own, with minimal supervision by humans.

[@haakoflo]

Cronin seems to be correct about the limitations of current LLM's, but I don't think he's correct in his view about the human brain. It seems that he considers the brain to be a Turing Machine, capable of performing computations that approach the magical, and with similarly magical free will / intentionality backing it. I say magical because he himself claims that "Free Will" (the way he defines it) breaks the laws of Physics, which is kind of the defintion of magic. However, if he's wrong, and we take the magic away and assume humans exist within the laws of Physics, it seems to me that most human brain activity are relatively similar to what we see in LLM's and other known neural network architectures. So far, the actual LLM's have been missing some of these capabilities, such as performing "reasoning", but I would argue that AlphaZero demonstrated very strong "reasoning" within specific domans years ago. And if you think AlphaZero is only a toy, then you're correct to a degree. But recent developments/rumors about Q*, Google's Gemini etc seem to indicate that similar capabilities are currently being integrated with LLM's, and currently providing reasoning capabilities at the level of a human child. And if we also remove the magical thinking about "Free Will", agency and therefore intentionality may be relatively simple to either insert or have emerge from training. So the vital point is not whether there exist any functions that cannot be learned by NN's, but rather if there are any functions LEARNABLE BY HUMANS that cannot be learned by NN's. If NN's can learn all functions that humans can learn, then AGI can be achieved with NN's (assuming the benchmark for AGI is "Human Level").

[@benbridgwater6479]

Intelligence seems simple enough. It's the ability of generalists such as humans to learn and adapt to a variety of circumstances, but I think we can express that in an extremely concrete and concise way: It's the (degree of) ability to learn from and use prior experience to predict the future. This includes predicting the behavior of of external entities (what that lion is going to do next), but also to predict (motor cortex output) one's own learnt actions and the effect they'll have. LLMs appear (and are to a degree) intelligent because they are trained with a predictive objective, and have the architecture (transformer) to learn from their experience and predict well. There's' a way to go from LLMs to AGI, but I'd say they are proof of prediction being the basis of intelligence, and there are many obvious next steps to make them more brain/animal like and predict better - become more intelligent.
