I can definitely see his argument, although I still do believe RISC-V did a lot of things better than x86...
I really do hope that the arch is eventually able to fix this. Better that there be an open ISA than them all be closed IMO.
He has good points, except he misses the goal posts completely.
Yeah...risc-v can learn from 50 years of x86 (among others). And yet.......
Better than x86 is a low bar when ARMv8 exists.
