Apple is reshaping its Siri division by replacing much of its existing team with engineers and leaders from the Vision Pro project. The changes are part of a broader effort to finally bring Apple Intelligence to Siri and fix long-standing issues that have held back its development.
Mike Rockwell, formerly in charge of Vision Pro, now leads the Siri team. Since stepping in, he has begun transferring his trusted Vision Pro colleagues into Siri’s core engineering, user experience, and architecture teams. The goal: boost Siri’s performance and deliver long-promised upgrades.
Key Hires and Their New Roles
Ranjit Desai will now head the underlying Siri systems. Rockwell reportedly believes Desai’s experience with low-latency systems will help Siri become faster and more reliable. Olivier Gutknecht is leading the user experience team, while Nate Begeman and Tom Duffy will work on Siri’s new architecture.
Other notable moves include Stuart Bowers, a former Tesla executive, who will focus on refining Siri’s responses. Long-time Siri veteran David Winarsky has also been reassigned to lead a new speech-focused team.
A Decade of Delays and Missed Promises
This leadership shake-up follows a series of internal missteps. Apple originally promised to roll out Apple Intelligence-powered Siri in iOS 18.4 this year. That launch has now been pushed to late 2025 or early 2026.
Insiders blame a decade of poor planning and slow management for Siri’s failures. In fact, reports say Siri’s current performance has gotten worse—just as competition from rivals like ChatGPT and Google Gemini heats up.
Despite these setbacks, Rockwell still leads Apple’s visionOS team, suggesting Apple sees strategic overlap between the two products.
What’s Next?
With Apple Intelligence at the heart of its future plans, Apple is betting on this bold restructuring to revive Siri and win back user trust. Whether Vision Pro veterans can deliver where others have failed remains to be seen—but expectations are high.
