Google Glass wasn't really AR, more like a smart watch taped to your face, so I can imagine there being little business adoption. HoloLens seems much more promising, but development still seems to be slow.
I'd love to see AR succeed but with the current price I doubt it'll gain popularity in the near future.
Bummer, I visited a museum* using HoloLens to bring a command bunker to life, and even though it felt a bit gimmicky, it was really interesting and I could immediately see it being super useful in tons of other museums (e.g. seeing dinosaurs, explain physics/astrology concepts, show vehicles that no longer exist, etc. etc.)
* Musée de la Libération de Paris - musée du Général Leclerc - musée Jean Moulin - yes, that's actual full name
