AR will become a game changer once the hardware is there, i.e. glasses than can be worn comfortably and anywhere. Everything before that is just practice for the software and UI.
I agree with the idea but not that we need comfortable glasses that we can wear anywhere. AR will be a game changer on my bicycle if my helmet can integrate it. AR will be a game changer when I'm bombing down a mountain on my snowboard, if my helmet can accommodate it. My belief is that we will get deep market adoption in these verticals before any practical general purpose AR is possible
