There is no a priori reason to believe that the pixel resolution will ever be that high. Not all technology we can imagine is actually possible.

Pixel density high enough for acceptable text is already possible, just prohibitively expensive. See Varjo's headsets, for example - at the center of the display they have 70 pixels-per-degree (for comparison the Quest 2 has about 20).

I don't understand this. I code and read in VR almost every day. With proper aliasing, it's extremely acceptable as is. Font characters per degree has to be increased, of course, but Quest 2 is about the same as a 720p virtual monitor.

Have you tried reading in VR?

I actually think pixel density is one of the easier battle to win. Getting a cheap, lightweight, strain-free device to users is the real requirement.

For now, I can't handle more than ~30 mins with any VR/MR/AR device, but if I can actually wear one for several hours and be productive using one - I will be convinced we've turned the corner on this tech.
