Every developed country is going to push for their own homemade chips. Japan used to make Sparc CPU's back in the day. Probably many others I'm not aware of.
They made 6502 and Z80 clones as well, nintendo used them iirc
Every developed country except Australia, perhaps. This government is atrocious. The record for highest number of bureaucrats per capita in the world is owned by Australia. All they know how to do is tax people. All the wealthy people have left, or are leaving.
Even x86! Bandai WonderSwan ran on an NEC-made 80186 compatible CPU.
