We're 2 years into it and one would expect they'd incentivize the hell out of making sure this niche device has all the gates wide open. You can't have a walled garden if it's just wall.
Where are all the fascinating weird experimental trippy spatial computing concepts that we were supposed to see emerge. Where are the drone interfaces, the medical simulation applications, the training paradigms. New forms of entertainment, I mean least they could do is ensure that one awesome AAA game Half-Life Alyx had been ported over for this thing.
The thing is there's still no actual platform for AR, and Apple took probably the very best shot at giving us one. Your other options are Meta's pile of React garbage "Horizon OS", or Android... which is Android. Sure Steam is great on the PC, but it's been proven pretty conclusively at this point that tethered devices are a dead end for niche hobbyists. Like it or not, visionOS is by far the only viable platform moving forward after Daydream and Fuchsia were abandoned.
