This is a good salad of truth, but I think it misses the point. VR is not going to happen for a long time, but this high status product is mostly about demonstrating the possibilities of AR, which is happening all around us with existing technologies. Apple has concluded that it will be worth it to demonstrate how information superiority and affordance will work in a $3k headset before the lightweight glasses become feasible. The applications for this product (sports, research, conferencing, gaming, etc) won't depend on real world interaction.

Yes, but the basics of computing (text input, pointing, selecting) haven't been worked out for the new paradigm. Like you point out, how information superiority and affordance work even in standalone applications hasn't really been solved. Without tactile touch components, it's very hard to interact with spatial data (one of the reasons CAD is so hard to learn).

I'd suggest that we'll need another 'mother of all demos' that solve some of these HCI problems, not just the fit and finish upgrade that Apple typically offers.
