Thanks!
As far as AR and VR go, they’ll definitely be a way to supplement a general UI style, but I don’t think simple interactions will become AR or VR anytime soon. So as there will be more AR and VR apps, most of them will stay relatively 2d, at least until some brain-machine interfaces that will allow for almost no-UI approach :)
I personally love AR (both using and playing with them) so it’s good that the technology went that way.
