The Vision Pro is not doing well. Apple has cancelled the next version.[1]
As Carmack says, AR/VR will be a small niche until the headgear gets down to swim goggle size, and will not go mainstream until it gets down to eyeglass size.
It was always the plan for Apple to release a cheaper version of the Vision Pro next. That the next version of the PRO has been postponed isn't a huge sign. It just seems that the technology isn't evolving quickly enough to warrant a new version any time soon.
What physics are you talking about? Limits on power? Display? Sensor size? I ask because I’ve had similar feelings about things like high speed mobile Internet or mobile device screen size (over a couple of decades) and lived to see all my intuition blown away, so I really don’t believe in limits that don’t have explicit physical constraints behind them.
Lens diffraction limits. VR needs lenses that are small and thin enough while still being powerful enough to bend the needed light towards the eyes. Modern lenses need more distance between the screen and the eyes and they’re quite thick.
Theoretically future lenses may make it possible, but the visible light metamaterials needed are still very early research stage.
I think both hardware and software in AR have to become unobtrusive for people to adopt it. And then it will be a specialized tool for stuff like maintenance. Keeping large amounts of information in context without requiring frequent changes in context. But I also think that the information overload will put a premium on non-AR time. Once it becomes a common work tool, people using it will be very keen to touch grass and watch clouds afterwards.
I don't think it will ever become the mainstream everyday carry proponents want it to be. But only time will tell...
Until there is an interface for it that allows you to effectively touch type (or equivalent) then 99% of jobs won't be able to use it away from a desk anyway. Speech to text would be good enough for writing (non technical) documentation but probably not for things like filling spreadsheets or programming.
