Exactly, I believe I read a Carmack article saying that you need 4K pixels per eye to get to a resolution where pixels are imperceptible (though presumably those with better than 20/20 would need higher).

That’s probably a few years away, but I’d be surprised if we don’t get there in 5-10.

Meanwhile, we need to build all the ui and OS code to drive such displays.

That said I’m not sure I’d sign up for using the current generation as my primary display device.
