He'd be over-reacting if Apple's competitors didn't have perfectly workable AIs already deployed.
I am a programmer, and write code all day long. I can ask Microsoft's Co-pilot or their Github agent for help, and Google has an AI baked right into Android Studio that will take my project context into account, and even offer to make the changes for me. It isn't always correct, it requires a bit of hand holding, but it's like having a junior developer sitting next to me 24/7.
The tech is here.
And Apple promised it would be on my devices.
Except, Apple hasn't delivered, at all.
I upgraded to an M4 MBP in a major part due to the promised AI. We're half way through the M4 cycle, and it's nowhere to be found. If Apple releases an M5 chip before AI, I'll have basically bought a MBP a year early based on false advertising, and have every right to be pissed.
EDIT: If Tim Apple had got on stage and said "We've been experimenting with this new 'AI' thing, and it seems pretty cool. Over the course of the next two years, we are going to start rolling out AI features for the iPhone 15 Pro, and all 16 series iPhones. By Fall 2026 when we've completed our internal AI roadmap we estimate 80% of active iPhone users will have access to some form of the AI features, and we think you're gonna love it", that would have gone over really well, without over promising. It's called setting expectations, and Apple
really dropped the ball this time.
