I find this very pertinent, because it shows that there really is a

could overwhelmingly go ARM, before long.  Then again, Intel and/or AMD
could have something up their sleeve, for all I know, but it's
nevertheless clear that Microsoft knows they can't compete on certain
things with Apple's chips, without adopting the new architecture
themselves, and the OEMs could follow the example.

Intel and AMD haven't been snoozing. AMD's Opteron series from about 8
years ago was ARM based but it never went anywhere. Build the software and
they will come. It didn't work for RT but with both Windows ARM and Linux
ARM versions they smell blood.

It will also get a bit confusing. Arm.com, the company, currently has
Cortex-A, Cortex-M, Cortex-R, and Cortex-X.  A is general purpose, with X
following A although they are vague. R is realtime and is very
specialized. M is the microcontroller line that I'm playing with on the
Pico W.  Apple was free to call their processors anything they want but an
Apple M4 is definitely not a Cortex-M4.

The x86 family started as an interim band-aid on an 8080 but IBM yada-yada
and the rest is history. It's been hard at work for over 40 years; maybe
it's time for retirement.
