Only for as long as Intel could afford to spend 10× as much on developing 
each chip generation as the RISC vendors could. It could because it could 
reap 10× the profits in return, but it can’t any more. Which is why you 
see ARM coming to the fore, and RISC-V appearing as the upstart 
challenger.

It’s a whole new ballgame now, and x86 is starting to look a little long 
in the tooth. Which is why even Microsoft recognizes it needs to spread 
its eggs outside that one basket, with its ongoing attempts to promote 
Windows on ARM (without much success, so far).

As I said above, RISC is still around and dominating the computing world. 
They’re not running Windows, because it was Windows that could not adapt 
well to them. Instead, they are running Linux.
