Yann LeCun, the renowned AI pioneer and former chief AI scientist at Meta, publicly criticized Alexandr Wang, the 28-year-old cofounder of Scale AI recently hired by Meta to lead its Superintelligence Labs, calling him “inexperienced” and suggesting he lacks a deep understanding of how AI research works. LeCun’s remarks came amid internal frustration at Meta over the progress of its AI projects, including the Llama 4 model, where he says results were allegedly manipulated, leading CEO Mark Zuckerberg to lose confidence in the existing AI team and restructure leadership. LeCun also warned that more AI talent could leave Meta due to strategic disagreements, particularly over the company’s heavy focus on large language models—which he believes are a dead end for true AI advancement—as he departs Meta to start his own research-focused company.
