Hmm, touchscreens are a good counter point, but I do think they might be replaceable with AR glasses. It doesn’t seem difficult to mimic a feedback mechanism with only visual feedback and/or a light vibration from the goggles themselves.

I actually think it may be the opposite: direct input like keyboards might be around longer simply because they don’t require you to be looking at your hands to use them. Both touchscreens and AR goggles do.
