Apple Inc. is undergoing a rare shake-up of its executive ranks, aiming to get its artificial intelligence efforts back on track after months of delays and stumbles, according to people familiar with the situation.

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.

After Apple publicly admitted that Apple Intelligence's most important feature would be delayed indefinitely, Siri now has a new boss.
