Curious to see how this goes. It seems to me it’s hard to match reality—for example, books, book shelves, pencils, drafting tables, gizmos, keyboards, mouse, etc. Things with tactile feedback. Leafing through a book typeset on nice paper will always be a better experience than the best of digital representations.
AR will always be somewhat awkward until you can physically touch and interact with the material things. It’s useful, sure, but not a replacement.
Haptic feedback is probably my favorite iPhone user experience improvement on both the hardware and software side.
However, I will never be able to type faster than on my keyboard, and even with the most advanced voice inputs, I will always be able to type longer and with less fatigue than if I were to use my voice—having ten fingers and one set of vocal cords.
All options are going to be valid and useful for a very long time.
