Tim Cook’s final WWDC keynote was built around a single, concrete answer to a question that has dogged Apple for years: what, exactly, is it doing about artificial intelligence?
The answer, delivered from the stage in Cupertino on June 8, is a rebuilt Siri powered by Google’s Gemini models. Not a vague roadmap. Not a promise for next year. A shipping product, with a dedicated app, multi-step command support, and integration into the Dynamic Island. That was the headline of Cook’s farewell address, and it is the centerpiece of the transition he leaves behind.
Cook announced in April he would step down as CEO, calling it the right time. The change takes effect September 1, 2026. He moves to Executive Chairman. Hardware chief John Ternus takes the top job. But the WWDC keynote was not a victory lap. It was a handoff, and the handoff was a bet on Google’s AI infrastructure.
Apple’s relationship with its own AI has been fraught. Siri launched in 2011, a year after Cook became CEO. It was a novelty then, a voice assistant that could set timers and answer trivia. It fell behind. Competitors poured billions into large language models. Apple’s efforts, rumored for years, remained internal. The company’s culture of vertical integration—owning the chip, the OS, the hardware—clashed with the reality that building a world-class AI model from scratch is a different game.
So Cook’s final keynote made a pragmatic choice. Partner with Google. Use Gemini. Build Siri on top of someone else’s foundation model.
That is a significant development. It is not an acquisition. It is not a secret internal project. It is a public admission that Apple, for all its hardware prowess, could not go it alone on the AI front. The rebuilt Siri is the most tangible outcome of that decision. A dedicated app means Siri is no longer a background service. Multi-step command support means it can chain actions—”Find the photos from last June and text them to my wife”—without losing context. Dynamic Island integration means it lives on screen, visible, interactive, not just a voice in the void.
The rest of the keynote filled in around that core. New Apple Intelligence features. Expanded child-safety tools. The next generation of Apple’s operating systems. All standard fare for a WWDC. But the Siri announcement was the one that carried strategic weight. It was the one that answered the question about Apple’s AI future with a name and a date, not a concept.
Ternus inherits that future. His background is hardware—chips, displays, the engineering that made the M-series processors possible. He is not an AI researcher. He is not a software visionary in the Steve Jobs mold. He is a builder of physical products. Steering Apple deeper into the AI era, as the company put it, will require him to manage a partnership with a direct competitor—Google—while maintaining Apple’s traditional control over the user experience.
Cook’s tenure, which began in 2011 after Steve Jobs’ death, saw Apple become one of the world’s most valuable companies. It also saw it fall behind in AI. The rebuilt Siri is Cook’s parting shot at closing that gap. It is a concrete product, shipping now, not a promise for later. That is the fact that defined his final keynote, and it is the fact that defines the challenge for Ternus.
