Its not true AR though. Its "record reality then display in VR". You're never looking at the world. Always through screens.
Why not just get a few projectors or more screens if you want digital environments?
That said, I think the "you're looking at a digital reconstruction of the world" aspect pretty interesting since it means, in principle, everything can be changed as you'd like. Why not turn day to night, night to day, redecorate, block out ads on billboards, re-paint your house, hang paintings, add an extra window to your wall, etc?
Without that, you'll be looking at an artificially "crisp" version of the world.
