Is there utility in ar/vr glasses? Are you enjoying reading and typing from your small screen with your neck turned to the ground? With a friction of getting your phone in and out of your pocket 20 times a day.
How could it not be obvious?
I'd love it if the tech gets there someday, but it's not yet clear how it does.
The utility benefit still has to outweigh the bodily detriment.
I think the most important aspect of this is that such glasses don't introduce a separation between you and the rest of the world.
If people using AR are disconnected from interacting with others in real life (which seems very likely), then there will be a social cost for using it on the regular.
I think this, more than any other single thing, is what will keep AR in the realm of niche applications. The similar problem with smart phones is already one that people complain about a lot. AR would only make it worse.
it's a quick (and mostly accepted) way to tune out, for example, while standing in a line or something. Yes, many people overdo it, but imagine popping on your VR helmet for a second in a social setting.
