Does somebody use both, current Intel and AMD tower PCs?

What is happening is the *ARM* Chips have caught up to x86 processors and will 
be blowing past, in terms of bang-for-the-buck, CPU processing power, and 
lowest power cost.  CISC chips (eg x86 flavors) have pretty much reached their 
"peak" -- at this point transistor size is pushing atomic limits (eg the size 
of a silicon *atom* is the limiting factor in transistor size).  CISC chips 
need more complex gate structures / more complex micro code than RISC chips. 
That is RISC processors need fewer transistors / simplier micro code to 
perform the same op, and thus can do more with less (transistors, micro code, 
power consumption, etc.).

Apple's M1 already out performs x86s.
