never said when it’s gonna change everything

All even half-way relevant architectures but x86 and z/Architecture are RISC nowadays: ARM, Power, MIPS (The Chinese tried to revitalise it but they seem to be switching to RISC-V), Atmel AVR. Oh speaking of microcontrollers: Z80 (CISC) still lives though arguably it’s genetically an x86. And then of course RISC-V which most of all is an open standard, and a clean slate. Also, the first vector insn set that also runs on hardware that isn’t a supercomputer.
