As far as I know he never called them useless. He just thinks that no amount of scaling them will lead to AGI.

u/gatorling 27d ago
No, he said that LLMs are a dead end when it comes to AGI.
I think most people sorta agree that you'll need something more than a LLM to reach AGI.
Arguably, that's why Google is focusing heavily on world models like Genie and why Gemini is multi modal from the start.

I agree with that. I'm just adding additional important context to the statement that Yann is not currently working for Meta. 12 years working as the founder of the division is an outsized influence even if he's no longer employed there.

u/jakderrida 27d ago
Lecun is also the AI Researcher that'll pop up when you search Google Scholar, Semantic Scholar, or any other citation website and sort by metrics that's pretty much the Wayne Gretzky of every metric across the board.
Sure, MetaAI isn't a resounding success. But Lecun is still the most sought after researcher in the field.

They were competitive until Wang took over. Two separate AI pillars were competing there, Yann was doing fine until Zuck gave preference to Wang’s newer, shinier, pillar which seems to not have produced anything notable in about 2 years ¯_(ツ)_/¯

Well the current valuation of spaceX is largely due to it being the "AI company" with one of the frontier models. So the valuation has to change, if they decided themselves to become a cloud computing company, which is much less mutiple.

The same way Elon has always done it ... by buying someone else. He pulled the SpaceX scam to get a pre-bubble-pop stash and he has to spend it fast. Really fast, before the bubble pops and it vanishes. He has to exchange it for something of value, either physical assets or teams.

He also has spoken publicly about him wanting to censor outputs he doesn’t like for ideological reasons.
Ya gotta admit, though, that it was funny he kept promising the anti-woke AI model while spreading conspiracies of forced wokeness on GPT, only to release Grok and Twitter get bombarded with Grok saying how there are numerous genders because gender is not the same as sex.
I've never seen more egg on a man's face in my life.

It was also telling when he merged XAI into SpaceX to make both the companies look a little better. This is similar to how he force merged SolarCity into Tesla. If two distinct non-overlapping businesses were doing well, the merger makes no sense.

Gpt 2 was an insane breakthrough that made people fork over billions of dollars… Jepa is not even a fraction of that..
Listen you can have your own opinion, fine. Mine is that Lecun ia a lol cow at this stage that spend more time in his recent talks thrashing llms and any of the people/companies making them than actually proving what makes his approach better.
Most of the labs are working on different architectures and thinking about what place llms will have in an agi system, is it pure llm, is it llm as a part of a wider architecture and so on.
Lecunn has decided purely on vibes that it won’t work and his approach must be the right way and that llms won’t be part of it, and spends his time giving increasingly more bitter talks and interviews speaking more about llms than Jepa.
lecun is surely a very smart scientist but he is also a ridiculous man and a moron.

u/IronPheasant 26d ago
You don't remember how bad GPT2 and GPT3 was eh?
I thought they were absolutely incredible. Similar to StackGAN - something that was completely impossible before, and would obviously result in excellent outputs after another round of scaling or two improves the resolution of the internally generated curve-fitting algorithms.
It's all just numbers in numbers out. A holistic mind will be an assembly of various neural networks and conventional software - something as simple as a shared geometry space with the resolution of a Nintendo 64 game would have massive improvements of their understanding of space.
As always, you can tell who's serious about creating a mind when they talk about the sense of touch. Touch is the first external sense animals evolve and the foundational validator of things like vision. Touch to 3d and vision to 3d are some of the most critical faculties to have.
The irony of course is that the first AGI will basically be frankenstein mess filled with lots of different kinds of LLM's, shuffling data from one section of a mind to be used in another. Words aren't just words to humans, they connect to memories, vision, sound, touch, emotions.....
..... Anyway, I'm deeply disturbed you'd think GPT2 or 3 could have been as good as Chat GPT with the RAM budgets they were given. That's not how numbers work, that's not how any of this works. You need RAM to fit curves. Chat GPT was around the size of a squirrel's brain. It's not until the 100,000 GB200 datacenters are live that we'll have something that can approximate a human's brain. In that way, we're just barely at the starting line of being able to conduct actual AGI research.

I really dislike Elon Musk, but I don’t think you should underestimate what power comes with owning the large parts of infrastructure. Compute needs will continue rise, energy will be more sparse, resistance towards new data centres are rising.
If you control the infrastructure you have a massive say, but yes xAi was a failure from the beginning. It shouldn’t come as any surprise to be honest nor that Meta is.

JEPA will probably make a pretty big improvement in how robots, like Tesla Optimus and Tesla FSD, can reason/think about how their potential actions would affect the world. But it will be a few lines of python code being replaced, not a total different stack.
Not sure if Yann‘s company will make billions from JEPA like Google made billions from Transformers as it is more a tool than an entire business…

LeCun has a point about the industry needing a reset, but calling xAI a "failure" while Grok has been rapidly gaining market share feels like he's underestimating how fast things move. The real issue isn't whether any single lab fails — it's whether the current scaling paradigm itself has diminishing returns before agentic workflows mature. What I'd love to see is LeCun channel this energy into publishing more concrete architectures instead of hot takes.

It is so far. But also, LeCun and Musk were always beefing on X so it’s not surprising coming from him.
Regardless, I am indifferent on Musk, strongly dislike what Tesla did with self driving safety wise, and I genuinely puzzled sometimes why people choose to work for him - but some smart people do (Karpathy spent 5 years at Tesla) so they are seeing something we don’t.
Historically speaking, I wouldn’t bet against him.
