Why would "consumers" as a whole care about an AI specific pc?

Consumers consciously choosing to play games - or serious CAD/image/video editing - usually note they will want a better GPU.

Consumers consciously choosing to use AI/llm? That's a subscription to the main players.

I personally would like to run local llm. But this is far from a mainstream view and what counts as an AI PC now isn't going to cut it.
