Re: RISC-V
:) We agree about some of that!
- RISC-V has been distinguishing itself in MPU / microcontrollers / co-processor class of chips.
- China is pushing consumer-class RISC-V hard, and will likely be pushing RISC-V kit (probably low-mid range performance) out in the relatively near future, to low-economy parts of the world. India, Vietnam (and perhaps Russia for obvious reasons) also want in on RISC-V. (Maybe the EU do too, with their worries about sovereignty.)
- Software for RISC-V is still an area which needs a lot of work.
But if you're looking for a company that is talking about mixing ISAs - look no further than Intel.
