Apple's WWDC 2026 keynote did three things at once: announced Tim Cook's retirement and John Ternus as the next CEO, rebuilt Siri on top of Google's Gemini models, and quietly seeded code for a foldable iPhone into iOS 27.

This episode breaks down all three. The Siri rebrand is the headline. The newly named "Siri AI" runs on Gemini through Apple's Private Cloud Compute layer, gets a standalone app, and adds real-time screen awareness plus personal context across apps. It's the first time Apple has handed its assistant to a competitor's model, and the privacy framing on stage was clearly built to answer the question that move invites.

The foldable iPhone story isn't in the keynote, it's in the code. Analysts pulled flexible display references and new app-adaptability tools out of iOS 27 betas, the strongest signal yet that the long-rumored foldable is closer than Apple is saying.

Then the platform updates. iOS 27 brings up to 30% faster app launches and supports every device back to the iPhone 11. macOS 27 "Golden Gate" drops Intel support and refines the Liquid Glass design system. The Health app added perimenopause and menopause tracking, and Apple Watch picked up updates aimed squarely at Garmin and Whoop. Expanded parental controls now require child accounts for under-13s.

Two things that almost got buried. Siri AI won't launch in Europe or China at first because of regulatory complexity, which leaves Apple's two largest non-US markets out of the headline feature. And this was Tim Cook's final WWDC as CEO. He hands the role to hardware chief John Ternus on September 1, ending a 14-year run.

We cover what it means for Apple's identity that the privacy-first company now routes its assistant through Google, why Ternus over Federighi is a hardware-first bet at exactly the moment AI is software-defined, and what foldable code in iOS 27 says about the iPhone 18 roadmap.
