what would be their motivation to switch? They already control everything they need to with Arm. RISC-V would not open any doors for them that are not already opened, as far as I can tell. It is far easier for them to adjust their existing silicon designs than to adopt an entirely new ISA, given equal gains. What we're going to see now is 20 years of solid innovation on Arm CPUs from Apple. I don't even like Apple at all, and that is apparent to me.
