Imagine they got into making an ARM CPU competitive with Apple's? Or a server chip that is better than Ampera's, and sold at scale? I think they have the expertise and ability to do it.

A dual-mode ARM-x86 core would be an interesting CPU that they certainly have the skill to create. Thanks to the protected mode descriptor model, imagine having ARM64, ARM32, x86-32, and x86-64 code segments all coexisting in the same system, with no emulation nor virtualisation. There wouldn't be any overhead, because all instructions regardless of ISA get translated to uops anyway. They could add a RISC-V front-end too, just for completeness sake.

  That sounds like dev and user experience nightmare.

  I can see AMD/Intel releasing RISC-V CPUs with x86 acceleration. I do not see it with an ARM mode, because there's no such software moat stuck on that platform as there is with x86.
