If you're going to bring in RISC-V, why not mention ARM? They're currently more of a threat to Intel than RISC-V and likely will be over the next decade. They have a near monopoly for anything that is not a computer that requires anything more than a low performance microcontroller, and are supported to varying degrees by the three major general purpose operating systems.

RISC-V likely has a promising future, but the foundations are still being laid.
