Yann LeCun’s new venture is a contrarian bet against large language models
Yann LeCun is a Turing Award recipient and a top AI researcher, but he has long been a contrarian figure in the tech world. He believes that the industry’s current obsession with large language models is wrong-headed and will ultimately fail to solve many pressing problems.
Instead, he thinks we should be betting on world models—a different type of AI that accurately reflects the dynamics of the real world. Perhaps it’s no surprise, then, that he recently left Meta, where he had served as chief scientist for FAIR (Fundamental AI Research), the company’s influential research lab that he founded.
LeCun sat down with MIT Technology Review in an exclusive online interview from his Paris apartment to discuss his new venture, life after Meta, the future of artificial intelligence, and why he thinks the industry is chasing the wrong ideas. Read the full interview.

Why 2026 is a hot year for lithium
—Casey Crownhart
In 2026, I’m going to be closely watching the price of lithium.
If you’re not in the habit of obsessively tracking commodity markets, I certainly don’t blame you. (Though the news lately definitely makes the case that minerals can have major implications for global politics and the economy.)
But lithium is worthy of a close look right now. The metal is crucial for lithium-ion batteries used in phones and laptops, electric vehicles, and large-scale energy storage arrays on the grid.
Prices have been on quite the roller coaster over the last few years, and they’re ticking up again. What happens next could have big implications for mining and battery technology.

One more thing
How electricity could help tackle a surprising climate villain
Cement hides in plain sight—it’s used to build everything from roads and buildings to dams and basement floors. But it’s also a climate threat. Cement production accounts for more than 7% of global carbon dioxide emissions—more than sectors like aviation, shipping, or landfills.
One solution to this climate catastrophe might be coursing through the pipes at Sublime Systems. The startup is developing an entirely new way to make cement. Instead of heating crushed-up rocks in lava-hot kilns, Sublime’s technology zaps them in water with electricity, kicking off chemical reactions that form the main ingredients in its cement.
But it faces huge challenges: competing with established industry players, and persuading builders to use its materials in the first place. Read the full story.
