I’m not so concerned with the instruction set. The differences are generally overrated.

I’m concerned about monopoly power. Out of three companies that can legally make modern x86-64 processors, AMD is the only one worth talking about anymore. Unless China wants to throw some major weight into restarting VIA’s x86 line, that’s not likely to change. China seems fine with ARM and RISC-V, and ignoring x86.

The competition on the horizon is no longer AMD vs Intel. It’s AMD vs ARM vs RISC-V.
