Earlier quoted context omitted.
I'm incredulous that having a screen strapped half an inch from your eyes for 8+ hours is desirable. I have an Oculus Rift, my face is sweaty/red in a couple of hours and there is an indent around my eyes. I'm sure newer tech can be much better, especially with airflow and an AR set that lets in natural light. We're not there yet, though.
I just got to try an Oculus Quest 2 and I was really blown away by how advanced it is, I didn't expect that. But at least in my case and at my age after a 2-3 hours of full use (when you run out of battery) my eyes are really tired and I was scratching them for a few days after. So, it still need one extra generation at least, probably an "iPhone-like" moment but it's definitely addictive.
The VR-sickness persisted for hours until I realized that the solution was to try and reset my system by walking outside and gazing at the horizon (which also works on seasickness to a point).
