I'd say it's similar to how games took a long time to transition properly to 3D. Most of the early 2.5D or 3D games would probably have done better in 2D. It's hard to say what was the first truly good 3D game, but at some point, we got Half-Life, then Counter-strike, and plenty of games now like Skyrim. Heck, besides Angry Birds, very few transitioned well to touchscreens. Touchscreen only works because it's a convenient platform, not that it's better at anything. I think it needs some creative effort as a lot of it is still groundbreaking, and people have difficulty thinking in the "real world" dimension. Remember, a lot of our current technology was probably influenced from sci-fi like Star Trek first. It took some inspiration for operating systems to go from pure text based to windowed, and some more time for users to accept it. It's possible the first practical use of AR might be like the Iron Man scene where Stark uses it to view the suit in 3D and manipulate the controls. It seems like Magic Leap is working on something like that for education.
