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 Quest gave me persistent "seasickness" after use the first half dozen times I used it (this was last winter, I had nothing better to do than see if I could get better at tolerating it). I eventually got more tolerant of it, but after not using it for a while I'm hesitant to pick it up again in case I am back to square one. During use I could handle stationary scenes okay, but the after-effect was nasty. An incredible piece of technology, though.

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).

In thirty years there will be a startup that you can get affordable eye replacements. Keep burning those eyes!
