My comment was meant to be more general than Intel. I’m even including AMD here. x86 has no presence in mobile (that ship has sailed) and again I’m seeing quite a lot of innovation on ARM side wrt server-class processors. Not sure how traditional PCs will play out but Macs are going to split off from x86 within years.
I totally agree, I think it would be a good thing if x86 were to be replaced by something newer. Intel could even adapt and continue to play a leading role, that is another question.
