I gather intel is betting heavily on RISC-V as something they can dominate. When they make a tasty CPU with this ISA then yes I think that we might welcome Intel to Reform.
As for x86, please no. Let’s not perpetuate an architecture that, in a rational world, should have been replaced by PowerPC (and others) back in the 1990s.
My objection is precisely that x86 is the safe, compatible, middle of the road choice. It is one half of the Wintel establishment that we are trying to rebel against, no?
I do have some sympathy to the compatibility argument because I like Haiku which does not yet run on ARM. But I can choose from millions of used x86 machines for much less than the Reform - machines which may be obsolescent but have more than enough muscle to run Haiku well.
