I don't care what GPU my mobile phone runs. It's fast enough, I'm ok with it.
I also don't care about servers. I'm not a dev-ops/admin person.
On my laptop/desktop, where I DO care, I don't see Intel going away anytime soon.
Even if we switched to some ARM devices, it would be a regression (if not for anything else, for having to run most Windows/MacOS stuff under some kind of Rosetta-like interpreter for many years).
Besides, as soon as ARM CPUs approach the limits of various manufacturing processes, they will face the same issues Intel does. Moore's law is not coming back.
