Yeah, POWER has basically unlimited nested virt from POWER9 on. And unlike x86 you don't get the massive slowdowns past a level or two of nested virtualization.
Stadia seems to think it can push a high resolution monitor like stream over a network interface. I'm playing devils advocate of course here but fundamentally if you don't have control of the hardware there's no long term advantage to local compute, at least not with current market trends etc. Everything points to a move back to dumb terminals for consumer use at this point -- in the past it would have at least been possible to hack those terminals to run some minimal (for the time) OS, but crypto locking of the terminal hardware stops that quite cold.
