Mark Zuckerberg’s most famous employee reveals what he hated most at Meta, the company he worked for more than 12 years

Yann LeCun, Meta’s former chief AI scientist, revealed he “hated being a director” during his 12-year tenure at the company. The Turing Award winner left Meta in November last year to launch his own AI startup, citing frustrations with management duties and disagreements over the company’s heavy investment in large language models, which he calls “a dead end” for achieving superintelligence.
