Apple's Mike Rockwell is reportedly considering leaving at least his current role as head of Siri AI, perhaps prompting a shakeup of executive roles at the company.
Rockwell was behind the development of the Apple Vision Pro and subsequently became head of Siri AI as Apple worked to revamp Siri into the version released in 2026. According to Bloomberg's "Power On" newsletter, though, he is seriously contemplating his future.
Reportedly, this could comprise his stepping down as lead of Siri AI during 2027. However, it might further mean his leaving Apple altogether.
The new report has no further detail, but speculates that if Rockwell makes either move, his current responsibilities would probably be shared between two people. Those are ex-Google AI veteran Amar Subramanya, and Sebastien Marineau.
At present, Marineau reports to Craig Federighi and reportedly there is some expectation that he will eventually replace his boss. Although as the report also notes, there is presently no indication of Federighi planning to either retire or leave Apple in the short term.
How Rockwell reorganized Siri A
Mike Rockwell only took over Siri AI in March 2025, following Apple "fixer" Kim Vorrath's assessment of that team. By April, Rockwell was replacing staffers with people from his Apple Vision Pro work.
This all led to the release of the much-revamped and much improved Siri AI, which was announced at WWDC 2026. But the change in leadership from John Giannandrea to Rockwell reportedly came after crisis talks.
