I think the big question is would we be better off with this technology?

For example, there have been times I would absolutely love to send a tiny drone into a tree to cut a branch that is in the way of the sun coming into the house.

That may benefit from AR, as it would be far too risky to produce a machine like that, that we can't have complete control over.

That essentially would be like having a detached floating limb that can fly around and act like a hand.

Do we want this sort of progress?

Do we need it?
