There's a difference between deep tech research (which truly can be revolutionary) and "revolutionary" consumer gizmos. I don't think the analogy holds.
For instance, just imagine wearing a set of AR goggles while <working on your car/building some furniture/whatever> and having an exploded parts diagram available at your beck and call in relation to the physical item in front of you, with assembly/disassembly steps shown should you so desire.
I can think of dozens of real world applications off the top of my head. AR assistance for challenging professional situations (surgery, mechanical repairs, etc), PTSD treatment, AR warfare, gaming, and so much more. And this is with our limited viewpoint in the year 2024.
When headsets (or the evolution of them) are eventually the size of reading glasses and cost very little, this could change the world.
