For the first two examples I gave I remember seeing an early adopter do exactly what I described and it was instant comprehension for me. Again-- it doesn't mean I knew those technologies would take off, that they'd be important, or even that I was excited about them. But it did mean I at least understood one glaringly obvious potential if they happened to take off. Also, the third example does not yet exist as a common vehicle so I cannot have hindsight bias. But again, glaringly obvious that reading a book instead of staring at the road for an hour would be an enormous gain in productivity and agency for lots of people. Or even take a failed futurism-- If I had a jet pack I could quickly fly on a whim to the beach and have a picnic. Instant comprehension. What's the cool thing I get to do that I currently cannot if my household appliances all send streams of sensor data to a third party?
