Hairsational Look at the past 3 years since the Quest 2 was released. The tech hasn't exactly progressed in leaps and bounds in that time. VR porn is still mostly the same today as it was back then, just with a few incremental improvements.
But look about 2 years further back than that at the Oculus GO. Or a couple of years even further back at Google Cardboard. Now the difference is enormous.
And I would argue that the difference in AR capabilities between the Quest 2 and Quest 3 in the span of 3 years is pretty significant.
