But it sounds like he’s already falling out with the man he hired to spearhead Meta’s renewed AI efforts, Alexandr Wang. Wang is the founder and former CEO of the AI data annotation startup Scale AI, which provides an essential service for training AI models, but doesn’t actually build them. LeCun viewed LLMs as a dead end and favored building new kinds of AI models instead. Some staff questioned Wang’s credentials to lead such an important effort, and it’s a fair point to raise because Wang’s company didn’t build AI models at all. Now, he’s expected to not just develop AI models, but the kind that would rival human intelligence.
