No disrespect to Spectacles, but camera glasses have been around for years. It's not AR and it's not yet even material to Snap's business (according to Snap!).
Right, but this goes back to the arguments everyone had about the iPod - MP3 players had been around for years, the iPod nailed the execution (eventually - the first version was not a success). Nor was it material to Apple's success, at the time. The point is that proven execution is a good thing, because it implies you'll do it again.
Anecdotally, it's been interesting to see GoPro take off over the years, spreading from "extreme sports pros" at the beginning to include more casual/recreational uses now. A lot of friends who wouldn't have considered buying a GoPro 5 years ago (because "they don't do anything exciting/dangerous enough to need it") are now considering GoPros to document the slightly more exciting parts of life. These same friends are even more strongly considering Spectacles, because Snap made a product that fits into their lifestyle (lowering the barrier of what is "interesting enough" to capture)
