- AR is very promising for both work and play, but is worthless shit if you have to hold a device to use it. Instantly 100x better if you've got hypothetical near-future non-terrible AR glasses on most of the day.

- Half of what people use the Web for is looking up trivia that would have been too high-cost to look up before, to bother with (most of the other half is posting on social media about it). Glasses further lower the cost of looking up many categories of trivia, making even more trivial pieces of knowledge cheap enough to look up. On a revealed-preference basis, this seems to be something people really like and find irritating when denied—nobody used to feel an itch when they couldn't find an answer to some fleeting trivial question that entered their mind. Once exposed to the Web, and even more so when smartphones were introduced and the Web became something you carried everywhere, they do, and it'll be the same for answering questions about stuff they're looking at, once used to glasses.

- The use case of capturing otherwise-missed (getting out the phone is too slow) fleeting once-ever moments is going to be very compelling for people.
