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.

In the process, the Siri team was reassigned to this new department and placed under Giannandrea’s authority. By early 2019, the new SVP was shuffling things around to refocus on longer-term research, presumably in hopes that taking the broader view would ultimately help Siri improve.

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.
