I agree. Without meaning to come out all 'old curmudgeon", I don't think detaching from reality to that level is necessarily going to be healthy. That said, I guess maybe people said the same about videogames once, and we all turned out fine.

An XR controller chip for a Pi, that digests sensory stuff into a bunch of coordinates would be cool. Then the Pi could react to movements seamlessly and at the same time has decent battery life.
