[@stevendenton8994]

a musing: As the final breath escapes the lips of a man whose wealth spans continents and cyberspace alike, the world holds its breath in anticipation. In a time where AI algorithms and genetic tracing techniques can swiftly identify heirs, the chaos that ensues is nothing short of monumental. Imagine the scramble for power, the desperate bids for control over trillions of dollars worth of holdings, amassed through centuries of cunning, deceit, and exploitation. The Napoleonic wars, World War I, World War II - each conflict a pawn in the game of empire-building, each battle a step towards amassing unimaginable wealth. But now, as the titan of industry and commerce breathes his last, the vultures begin to circle. In boardrooms and war rooms alike, plans are set in motion, alliances forged and broken, as nations vie for a piece of the pie. For some, it's a chance to claim what they see as rightfully theirs, a long-overdue reckoning for past injustices. For others, it's an opportunity to consolidate power, to reshape the world in their own image. And yet, amidst the chaos and bloodshed, there are whispers of something darker, something more sinister. Could this be the spark that ignites a new world war, a final showdown for dominance in a world teetering on the brink of transhumanist revolution? Could the quest for power and wealth lead to unspeakable atrocities, to genocide on a scale never before seen? It's a chilling thought, one that forces us to confront the depths of human greed and ambition. In a world where technology has blurred the lines between man and machine, where the boundaries between nations are becoming increasingly porous, the potential for destruction is limitless. And yet, amidst the chaos and despair, there is also hope. Hope that, in the face of adversity, humanity will rise above its baser instincts, that we will come together as a global community to build a better world, one where wealth and power are not the ultimate measures of success, but where compassion, empathy, and justice reign supreme. But for now, as the world waits with bated breath, the specter of war and genocide looms large, a reminder of the fragility of our existence, and the darkness that lies within us all.

[@arssve4109]

Quite fascinating! The conversation puts LLMs into perspective for me - they too are representations of the world, but they still rely on us decrypting the language representation into the real world manifestations. We are still the only ones that know how to map our language to the world dynamics, because we each have decades of training into this. If I understand the argument is that AGI would need a model of the physical world dynamics, as well as it's mapping to language, to 'understand' the meaning of language.

[@arunprasath9586]

Nicely summarized!!

[@dibbidydoo4318]

Symbolic mathematics is the same thing exact thing as language. Mathematics requires understanding the patterns of the real world to have numerical cognition and number sense that we can transform into symbolic mathematics. We won't get any new form of mathematics by just training LLMs on math equations and problems.

[@AwkwardDog]

Like Helen Keller

[@antonystringfellow5152]

This is already happening with multi-modal models. Unsurprisingly, models trained with video as well as language perform far better than separate models trained on just one then connected together. This is how we humans learn - we make connections/associations between the data as we're being programmed and storing memories (two separate processes). We have general intelligence precisely because we are able to form so many associations. Even the best models we have today are still severely lacking in this ability. This may be a result of architecture rather than scale. The human brain is immensely complex, being made up of neural networks consisting of around 100 neurons each, with an estimated 700,000 synapses, and it has about 300 million of these neural networks in total. I'm not sure the current AIs have quite that degree of complexity. Another thing the human brain is very good at is filtering out data. In fact, the majority of the data streaming from our eyes never reaches our conscious brain at all. Edited to add: In the human brain, the 300 million neural networks are connected together hierarchically. Forgot to add that and I'm sure it's a critical point.

[@Steve-xh3by]

I'm confused over the claims made on the limitations for predicting video. Don't technologies like Nvidia DLSS and AI upscaling fill in missing visual data in an almost imperceptible way already?

[@10ahm01]

filling a gap between two instances and trying to predict the gap after the last one are completely different tasks.

[@ktome1087]

Upscaling is like going from a crayon drawing to a detailed drawing using colored pencils. It’s using deep learning to increase detail/resolution via motion data and feedback from previous frames. Almost like tracing. But video prediction would require the ssi model to not only interpret each frame of a video but also understand the sequence of frames and extract complex patterns from it. The latter is much more difficult. Think of an SSI model being shown the first half of a video of a race between two cars, and after only seeing the first half, potentially being able to predict the second half of the video of the race. That’s potentially what self supervised learning models can accomplish

[@Steve-xh3by]

@@ktome1087 But DLSS fills in missing pixels, no? It has to predict pixels to upscale. I don't understand how that is miles different from producing the whole next frame. It seems like you could use some stitching process and movement prediction based off the previous frame.

[@knowlen]

​@@Steve-xh3by I think the fundamental issue is that we train sequential models to predict the most probable sequence. Text is discrete and non-differentiable; as you add words to a sentence you reduce the branches of plausible completed sentences (like pruning timelines). Videos do not share this property, if anything they have the inverse property; as you add visual information (eg; objects / entities) the branching over plausible sequences explodes. DLSS sidesteps this problem by depending on information from a game engine --it doesn't have to predict what is going to happen because the engine will tell it what happens. People do use "stitching processes" (eg; computer vision techniques like area correlation) to try and sidestep temporal modeling; have you ever seen a deepfake where something in motion becomes excessively blurry for a few frames? or where the textures on some object seem to flip every frame sort of like a stop-motion film? It works well for DLSS because you can expect the distance between frames at high FPS in pixel space to be small. Sora is new in that it uses a transformer to somehow (successfully) force a diffusion model to stick to one plausible sequence when generating. The exact technical details of this are still unknown, but it appears to be another scaled solution thing. Like if you look at the examples from their smaller models the sequences break down as you'd expect.

[@ktome1087]

@@Steve-xh3by dlss is essentially a tool to achieve more resolution. SSI however is a tool to literally predict subsequent frames, which in a simplified analogy would equate to going from little league to the major leagues.

[@osuf3581]

​@@dibbidydoo4318 - Most of the notable researchers and in particular the two far more accomplished Turing award winners frequently call LeCun out for being wrong; or he claiming they are. LeCun is known to be frequently wrong. He is also not an active researcher. The only reason some are fanboying over him is because they like the implications of what he is saying while ignoring that he is at odds with the actual field.

Lex, Please add a playlist of your interviews on AI. Include a summary video of what you believe are their key points to compare & contrast the expert opinions then offer both hope & risks for an AI future. If you were AI king with unlimited resources, which problems would you point AI at & why? Which AI experts do you respect most & why? Where would you invest?

[@getgal1]

Yann has a way of reassuring everyone about the security and benefits of AI through his historical perspective.

[@praveenkumarak726]

Watching this in episodes, but a question already within the first 20 minutes or so. Was this recorded before or after “Sora”? Isn’t the statement about a latent representation of a world model with spatio-temporal compression into a patch sequence demonstrated with that? How different is this joint embedding mentioned here different to that?

[@xewi60]

Sora is using labeled videos, It's "cheating" in a way by using language

[@DavidOndrej]

"The danger of concentration of power in proprietary AI systems is a much bigger danger than everything else." Couldn't agree more.

[@yvonnehyatt8353]

Thanks , Lex for this broadcast,it is good. Please have on Daniel Priestley thanks,

[@leadgenjay]

Fascinating insights from Yann LeCun on the potential and limitations of AI. For entrepreneurs diving into AI, understanding the difference between model architectures like JEPA and traditional LLMs can be crucial for innovating in the space. JEPA's joint-embedding approach can lead to more efficient learning from fewer examples, which is a game-changer for startups looking to leverage AI with limited data.

[@sebastiananderson8679]

Finally! Super cool to hear from Yann himself.

[@therainman7777]

He is both laughable and dangerous at the same time. This is a guy who responds to concerns over the dangers of artificial superintelligence by saying (literally) “engineers will simply make the superintelligent AI safe-they made airplanes safe, so why can’t they make AI safe?” He either has childlike naïveté or he is deliberately spreading misinformation as a form of PR for Meta. Even his own colleagues are laughing at these pronouncements of his.

[@onlypencil]

was this recorded before sora was revealed because he mentions that ai cannot predict video. Im pretty sora is waas doing what he was talking about, or am i wrong?

[@dusanbosnjakovic6588]

This video was made by Sora lol

[@kekekekatie]

This is exactly what I was wondering - seems to conflict with the whole SORA bombshell, not saying I'm not impressed with how smart this guy is though.

[@ElenaS-de9hq]

😂

[@joemarklin]

Its not doing that, its creating something from scratch that has continuity, what he is talking about is taking a video that has already been created and taking segments or pieces out of it and seeing if AI can fill in the missing pieces

[@CuriosityIgnited]

Yann's vision of a future with open source AI empowering humanity is TRULY inspiring. Imagine how much good we could do if everyone had access to AI tools to augment their intelligence and capabilities, while preserving diversity of thought. An open, decentralized approach is critical to unlocking AI's benefits for all. Let's work together to make this positive open source AI future a reality!

[@xman933]

Isn’t Sora an example of a LVM (Large Video Model) that is trained on visual patches instead of text tokens, something he seems to suggest has not been mastered yet?

[@LtheMunichG]

Not sure. There were other AI video generators before Sora so it’s just a much better version. And he must be aware of that.

[@ritpatidar2678]

He is talking the reverse. Watching video and then understanding it.

[@donaldstrubler3870]

This now makes the entire Yann v Yud "clash" hilarious. This is a different level of intellect

[@therainman7777]

Yes, a much weaker one. LeCun made some important contributions, no doubt. But most were many years ago. In more recent years, he displays a shocking amount of hubris and has been wrong on nearly every prediction and claim he’s made recently. Please, _please_ do not listen to this guy’s BS and think that’s he’s some kind of wise sage. He has been wrong about virtually everything in recent years and it seems extremely clear that he is more of a one-man PR team for Zuckerberg/Meta than an actual scientist attempting to find the truth.

@@therainman7777 Accurate

[@MitchellPorter2025]

Yann's knowledge of (present-day) AI is superior but his anti-doomer arguments 2:08:48 could be rebutted by a high school debater. AIs won't have a will to dominate because we'll never make them that way. Or if we do, there will be AI police to stop them... You won't have your judgment warped by AI propaganda because your own AI will filter everything on the net before you see it (!)... We'll be making smarter and smarter AI and figuring out safety as we go along, and if anything ever goes wrong, it will never lead to anything irreversibly out of control, even though they will be smarter than the people in charge of the design process... I won't say that such a future is impossible, but this is literally a utopian scenario in the bad sense, that it is counting on certain obvious things to never go wrong. The "defense" provided by Yann's considerations is extremely flimsy, and if you actually don't want those things to ever go wrong, you would need a culture and regime of AI development more like what is associated with Yudkowsky.

[@davidw8668]

​@@therainman7777 who are you to make such allegations?

Yud isn't an intellectual, nor did he ever contribute meaningfully. He's rambling some fear based nonsense based on science fiction fantasies.

[@MendicantBiases]

i used to think the same way lex does about language being able to model an agi untill i was listening to this show on cbc radio. it was about a woman who slipped and hit her head in the bathroom and lost the ability to comprehend language, speaking or listening. she goes on to talk about how she met this man who was also learning language at an older age since he had spent all of his life around deaf people with no kind of sign language. the way they would communicate with each other was to act out the actions they recalled, like a stage play. the guy goes on to talk about how he had to wrap his head around the concept of words being attached to objects and ideas. there is more to it but i cant remember and cant find it right now but this totally destroyed my idea of intelligence being birthed from language which is what yann is saying about animals being about to live in the world and communicate and all without using words. To lex point though, language perhaps could be used as a vehicle of information that an agi can learn from but the underlying architecture of it cant be completely language based. idk if this is what lex was trying to say but i feel like sometimes the way he talks is like he has pink sunglasses on viewing the world, which isnt a bad thing but i feel like maybe it leads to confusion about the ideas hes trying to get across
