A few weeks ago, Professor Yann LeCun, widely celebrated as one of the “godfathers of AI,” stood in St James’s Palace receiving an honour from King Charles for his groundbreaking work in deep learning. Today, he’s preparing to walk away from Meta after 12 years, marking one of the most symbolic exits the AI industry has seen in recent years.
LeCun, known for his pioneering research, signature bowties, and unapologetically bold opinions, has chosen to leave the comfort of Big Tech to pursue a radically different vision of the future of AI.
And the timing is interesting: it comes at a moment when global enthusiasm for artificial intelligence is clashing with rising fears of an “AI bubble” and growing uncertainty about what comes next.
Why LeCun Is Leaving Meta
LeCun announced his exit in a series of posts on Threads, thanking Mark Zuckerberg and calling Meta’s Fundamental AI Research (FAIR) lab his “proudest non-technical accomplishment.”
“The impact of FAIR on the company, on the field of AI, on the tech community, and on the wider world has been spectacular.”
Under his leadership, FAIR became one of the most influential research labs in the world, driving advancements in machine learning, computer vision, and translation.
But Meta’s priorities have shifted. Like most Big Tech companies, the company is now heavily focused on large language models, the engines behind today’s generative AI tools.
And that’s exactly where LeCun draws the line.

Why LeCun Thinks the Industry Is Wrong About AI
LeCun has been increasingly vocal about his skepticism toward LLMs as the path toward human-level intelligence. While the rest of Silicon Valley races to build bigger models, he argues that:
- LLMs rely too heavily on text training data
- They lack the reasoning capability required for real intelligence
- They can’t replicate how humans, especially children, learn.
His alternative?
A new approach, he calls advanced machine intelligence, which relies on visual learning rather than massive text datasets. In LeCun’s view, the path to true intelligence looks less like ChatGPT and more like how babies explore and understand the world.
This puts him at odds not just with Meta, but with some of his fellow “AI godfathers,” Geoffrey Hinton and Yoshua Bengio, both of whom have expressed concerns about AI posing risks to humanity.
LeCun calls such fears
“preposterously ridiculous.” “Will AI take over the world? No. This is a projection of human nature on machines,” he told the BBC in 2023.
A Visionary or an Outlier?
While many celebrate LeCun’s brilliance, not everyone sees him as the industry’s clearest prophet. AI expert Gary Marcus recently noted that while LeCun has made undeniable contributions, he has also dismissed opposing views for years, often overlooking work from colleagues, including Marcus himself.
Still, whether you agree with him or not, LeCun’s departure marks a turning point. He’s not just quitting Meta. He’s challenging the direction of the entire AI industry and staking his career on a different future.
What Happens Next
LeCun says Meta will remain a partner as he launches his new company. But his decision signals a deeper shift: Big Tech’s grip on AI research may no longer be as secure as it once was.
If the AI bubble bursts, if generative models hit a ceiling, or if public trust continues to erode, the industry may look back at this moment differently.
It may be remembered as the moment one of its boldest thinkers stepped aside and chose to build something new.
