True. Then we cross a threshold where things that weren't even thought as possible become reachable, and we're back on the treadmill.

That's what we're having with VR: we came to a point where increasing DPI for laptop or phone seemed to make no sense; but that was also the point where VR started to be reachable, and over there a 300DPI screen is crude and we'd really want 3x that pixel density.
