I can see two game changing practical use cases directly:
Releasing computer people (and most others) from slavery to a desk when working -- including meetings. For personal interaction, you would need to stay inside ca 50-100 milli seconds distance.
Giving information to people when they need it while repairing/building/driving/etc a physical object.
I think definitely your second example, possibly your first, could be accomplished with "Soft" AR. Remote personal interaction would still be reliant on the latency of the network/medium, and without touch, I'm not sure how much more use superimposing someone believably into my field of vision would be as opposed to having a display or a holographic avatar of some sort that doesn't require full Hard AR.
