I think you're assuming a lot of things about mainstream users. If AR was that intuitive, it would have already been mainstream. Many apps tried to port existing good old text based interface into AR but none have yet to gain traction. You need to remember the mainstream users do know how to use computer and do know how to access websites and enter forms. But they do not know how this geeky augmented reality technology works. Also my point here was not criticizing AR itself, I'm just saying his approach makes things needlessly convoluted for the sake of making it look cooler.
