alt Hacker NewsI think MIPS is a great example, and even there I don't think there's the bizarre bifurcation of ISA options RISC-V brings to the table.
As a fellow olderster, I can't help but think that after almost 50 years of "ISA X is sooooo much better than x86 it's obvious ISA X is the future and x86 will be dead Real Soon Now (for whatever todays version of x86 is)" I can only shake my head ruefully and say "ping me when that happens".
Controversial Take (that history proves isn't): Software matters; ISAs don't.
x86 chips don't truly exist anymore. They only use it as a compressed ISA for a more capable internal representation that can be freely updated at any time.
