I'd love for all devices to be on the same architecture, console manufacturers figured out that if they use the same architecture as their partners, they'd have about as much ability to get a port than the others.
and given that RISC V is much more powerful and less battery hungry than the other architectures, and that all they'd have to do is to take ARM and adapt that, we could see computer renaissance.
Honestly We've been needing this since forever. X86 has become such a power hungry monster that it's just not worth using it for any mobile device.
I see Risc V and ARM becoming the future of computing for the average user
