Mostly presupposed hardware issues. Based on very thin assumptions, and some opinions that just seem wrong - for example, wearing a Quest 2 with the Elite strap is pretty comfortable, by far the largest issue is heat buildup and pressure around the eyes. The apple headset being lighter and with the much wider band looks to me it would actually be more comfortable.
The failure of 3D movies is always used as a cautionary tale, but it was a pretty unique case that came down to artistic execution. Both Avatar movies are incredible in 3D and don’t generate any kind of discomfort, but the average “3D” title from other studios was a cardboard-cutout mess, usually a worse experience than it’s 2D counterpart. Not a technology adoption problem.
