Yann LeCun left Meta after twelve years to build a company from scratch. Not because Zuckerberg turned on him. Because the machine did. LeCun: “It’s a project Mark Zuckerberg really likes. But over the last several months he and I both realized the potential spectrum of applications was beyond what Meta was interested in.” He had the CEO. He had the most influential AI lab on the planet. He had the resources. He did not have the one thing that mattered. A company that could afford to be wrong about LLMs. Meta had placed hundreds of billions behind a single bet. Every hire. Every roadmap. Every quarterly target. All locked into the same trajectory. Dissent was not forbidden. It was just structurally impossible. LeCun: “Right now, they are sucking the air out of the room anywhere they go, and so there’s basically no resources left for anything else.” So he walked in and told Zuckerberg the truth. LeCun: “I can do this faster, cheaper, and better outside of Meta.” Zuckerberg’s response: “OK, we can work together.” That is not a story about a bad boss. That is what happens when a company commits hundreds of billions to one direction. The institution becomes the ceiling. Even the man who built the lab could not think above it. LeCun has spent a decade as the loudest dissenter in the room. Not because LLMs are not useful. Because predicting the next word is not the same as knowing what happens when you drop a glass. A four-year-old child absorbs more sensory data in a single year than every LLM ever trained on text. Everyone inside Meta understood this. Nobody inside Meta could say it. He walked out. Raised $1.03 billion in four months. Jeff Bezos led the round. Nvidia backed it. The man who co-invented deep learning is not building a better chatbot. He is not racing to win the current era. He is building what ends it.


I've never sen anything more accurate


My read on "normal policymaker & corp. leader on AI": mostly now they don't need to be convinced it is very important (unlike a year ago). But they still see its capabilities as today + epsilon. So just briefly, here is what even "AI is normal tech" folks in the labs believe: 1/8


Nobody is skeptical of autonomous elevators because nobody alive today was even around to see a human elevator operator in real life before the last one got laid off. Automation is far safer.





🚨NEWS: Elon Musk’s last two xAI co founders have reportedly left the company Manuel Kroiss and Ross Nordeen are now out, meaning all 11 original co founders are gone Elon Musk says xAI is being rebuilt from the ground up.

@wholemars They have no idea how hard FSD is. Only path to success imo is hardcore real-world AI software with dedicated NN inference acceleration ASICs in car, multibillion dollar NN training supercluster and 10+ billion miles of vehicle data. Good luck.

Elon Musk: “Optimus is a general-purpose, sort of, worker droid. The initial roles for Optimus would be in work that is repetitive, boring, dangerous— Basically, work that people don't want to do unless they're paid to do it.” And Optimus has two legs/hands and 10 fingers because, “Humanity has designed the world to interact with a bipedal humanoid with two arms and ten fingers. So, if you want to have a robot fit in and be able to do things that humans can do, it must be of roughly the same size and shape and capability."

Nobody wants to read AI-generated books, watch an AI-generated movie or listen to an AI-generated song.

Always good to keep screenshots of the claims of Altman so you can see the pattern of his deliberately misleading predictions over time. This is from January 2025. Given failed outcomes this could potentially go to court as "misleading investors".

The task of rationally distributing resources for a multifunctional company has always been one of the most important, especially for an industry leader. In this sense, OpenAI’s decision to discontinue its Sora video service in order to focus on more important tasks looks encouraging. Meanwhile, Musk consistently promoting videos of beautiful women while Grok is still unable to create science & tech graphics with the quality required by the editorial teams of scientific journals seems a bit naive for an entrepreneur of his scale.

openai discontinuing Sora to free up compute for its next big model says a lot i'm glad they're focusing more on reasoning, coding, and research -- and that sora was not profitable enough to keep those resources still, i think they're building an omnimodal model maybe gpt-5o, with video
