Assuming AI means LLM, at this stage I've come across two broad categories of implementation that are actually interesting and useful to me as a user.

1) A box on the screen where I can chat with one to do ideation or really anything I want.

2) A command-driven approach where I hit a hotkey, type a prompt and the response is dumped out in front of me, possibly I had some text selected which heavily influences the response.

These are both pretty cool tbh and developers will have a field day for years finding sensible ways to incorporate them into programs.

None of this has anything to do with driving the hardware upgrade cycle since most of the models are running in the cloud. But driving hardware upgrades is what these marketing people are really trying to do when they talk about AI PC. They are irrelevant people, but they need to convert everything they see into a reason to buy a new PC.

That's what they get paid for. Monkey marketer see trend, monkey marketer do marketing. Monkey steal your attention.

Maybe a LLM will replace THEM soon. After all it's basically a digital version of the million monkeys on typewriters...
