Apple just delivered its most consequential WWDC keynote in over a decade. And it wasn’t just because of the AI announcements.

The June 8 keynote at WWDC 2026 served as Tim Cook’s farewell performance as CEO, a role he’s held since 2011. Cook will transition to executive chairman on September 1, 2026, handing the keys to John Ternus, Apple’s Senior Vice President of Hardware Engineering and a 25-year company veteran. The leadership change was first announced on April 20, 2026.

Siri gets a brain transplant

The revamped Siri AI features enhanced conversational abilities, on-screen awareness, and personal context integration. On-screen awareness allows Siri AI to understand and act on whatever is currently displayed on a user’s device. Personal context integration means the assistant can draw from a user’s habits, preferences, and data to deliver more relevant responses.

Apple emphasized that these features lean on on-device processing rather than shipping everything to the cloud.
