Is that really an issue? Eg it's the same with games, the better your hardware, the more likely you can play a new game at higher settings with better performance, with most cheaper devices outright unable to handle anything recent.

But if you wait a GPU generation or two, the performance has improved enough that you can do that with a much cheaper GPU.

There are already people working on distributed solutions to that problem. There are a lot of people working on these problems.
