Meta基础设施负责人离开，AI竞赛中能否保持优势？

santosh janardhan, meta's longtime head of infrastructure and co-head of engineering, is stepping down from his role. he will be replaced by dave brown, who joined meta as vice president of infrastructure earlier this year after spending 19 years at amazon, where he focused on compute, cloud, and ai. janardhan, who originally joined meta in 2009, helped the company grow into a social media and tech industry powerhouse and was recently tasked with leading meta compute, a company initiative to scale its data center investments and strategy. his departure comes as meta's investment in infrastructure has exploded in recent years as it seeks to keep up with competitors in the ai race.
