the difference is a personal computer is a vaguely-shaped thing that has a few extremely broad properties and there is tremendous room inside that definition for things to change shape, grow, and improve. processor architecture, board design, even the methods of powering the machine can change and you still meet the basic definition of "a computer." for better or worse, people saying AI in any capacity right now are referring to current-generation generative AI, and more specifically diffusion image generation and LLMs. that's a very specific category of narrowly-defined technologies that don't have a lot of room to grow based on the way that they function, and research seems to be bearing out that we're starting to reach peak functionality and are now just pushing for efficiency. for them to improve dramatically or suddenly and radically change would require so many innovations or discoveries that they are unrecognizable. what you're doing is more akin to looking at a horse and going "i forsee this will last forever because maybe someday someone will invent a car, which is basically the same thing." it's not. the limitations of horses are a feature of their biology and you are going to see diminishing returns on selectively breeding as you start to max out the capabilities of the horse's overall design, and while there certainly will be innovations in transportation in the future, the horse is not going to be a part of them.
