Mike Rockwell, the Apple Vision Pro chief, has replaced John Giannandrea as the executive in charge of Siri, in an executive shakeup to try and rescue Apple's flailing AI efforts.

Apple is replacing the head of Siri, shortly after pushing back the rollout of its highly-anticipated AI features, according to a report from Bloomberg. Mike Rockwell, the head of Vision Pro development, will reportedly replace John Giannandrea as the leader of AI and Siri.

Apple is reportedly shaking up its executive ranks, shortly after it delayed the personalized Siri features that it previewed at WWDC last year.
