One of them being Torvalds, the transmeta guy (also known for Git, and a couple other hobby projects)
Now I tend to fall on your side of this argument, but I have to say I'd like to see the formal proof of cluelessness :)
Having read previous iterations of the same arguments, I've yet to see anything quite that decisive.

- znwu 4y agoOn ISA design, it is just so wrong to endorse the opinion of a single person. ISA design has three significant parties of interest: IC designers, compiler authors, and software developers. No one can master these three fields all at once. No one. Not even Linus (who would be a master software developer + a decent compiler specialist).
- jhgkjhlkhjkljk 4y agoJim Keller has said ISA doesn't really matter beyond something like 15 necessary extensions.
- snvzz 4y agoSame Jim Keller has great things to say about RISC-V. Which, by the way, includes mention of much attention these few important instructions (not extensions) got.
