AR will definitely be the way forward for all computing. This brief awkward period of 50ish years using analog inputs and physical screens which we are currently living through will be seen as a blip in the history of human-computer interaction hundreds of years from now. However the only use case for this iteration of the technology is for developers to begin working on new interaction paradigms and app ideas for AR in general. We're still years away from true consumer tech but I can admit as someone very familiar with VR/AR hardware that the Magic Leap One is a solid evolutionary step forward from what we've seen so far. I'm not impressed enough to buy one yet, but at least the company has shown they aren't total vaporware at this point and hopefully they can keep improving.
