There is one place where a lot of people would appreciate more AI: app construction. Eric himself used a LLM to develop a zooming tool for iPhone. Ultimately, an intelligent computer would allow users to build exactly the the tools they need to get the job done without having to search the App store or the web. Such a thing could be wildly popular – you just tell the thing what you want, and it says "like this?" and you say "well, that is almost it but do this and this and put this here."
Of course, Apple would lose a fair bit of App store revenue, but they would make it up somewhere. Content delivery, I suppose. The upside to everyone being able to write their own apps is you would not have to worry about your own computer installing spyware trojans as part of that process.
Maybe they will come up with the middle-ground on that: the magic trackmouse – a flat trackpad that is big enough to ride a mouse over, which also charges the mouse inductively, and lets you do all kinds of new things that combine gestures and mouse action. Though, given the prevalence of notebooks, the mouse is kind of not as popular as it used to be.
