Apple Loses Senior Siri Executive and 4 More AI Researchers as Talent Bleed Resumes
The revamped Siri is expected to launch with the iOS 26.4 update. This update is expected to enter beta in February 2026 and be officially released in early March or April.
Looking at the recent string of departures, it appears that Apple's AI talent bleed is showing no signs of slowing down.
Mark Gurman: Apple Loses Key Siri Executive and 4 AI Researchers in Recent Weeks
Bloomberg's Mark Gurman revealed today that Apple lost **Stuart Bowers** to Google DeepMind. Bowers was one of Apple's most senior executives working on the Siri project, reporting directly to Mike Rockwell, head of the Siri division.
Apple has also lost four AI researchers: Yinfei Yang, Haoxuan You, Bailin Wang, and Zirui Wang.
This talent drain comes after Apple already lost four key executives in December 2025.
The exodus began after **John Giannandrea**, Apple's head of AI, stepped down in late 2025, with Amar Subramanya from Microsoft taking his place.
Shortly thereafter, **Alan Dye**, Apple's UI design lead, moved to Meta.
Apple then announced that **Kat Adams**, general counsel, and **Lisa Jackson**, vice president of environment, policy, and social initiatives, would be leaving the company soon.
Of course, Cupertino giant Apple is also losing key iPhone design team members to 'io', Jony Ive's company. io recently developed an "iPhone killer" device for OpenAI.
According to Bloomberg's Mark Gurman, OpenAI has hired about 40 Apple engineers in the past month alone! This includes prominent figures such as manufacturing design specialist Matt Theobald and human interface design lead Cyrus Daniel Irani.
Furthermore, Abidur Chowdhury, a rising star at the company that designed the iPhone Air, recently left his stable job to join an unnamed AI startup.
Bowers' departure is particularly painful. He is expected to work on Google's Gemini AI model, which will be the basis for a customized variant of the Siri model that will be released in a few months.
