Point: Don Norman on Google Glass. Read also I Go To A Sixth Grade Play, which is spot on. In theory, you can record everything and live totally seamlessly and not just miss a large portion of your life. In practice, we'll keep futzing with cheap, poor imitations, destroying the experience itself to get a recording nobody will ever watch. We're obstructing the experience by recording; it is possible to intensify it, as by a master photographer or artist, but we are usually not doing that.
Really killer point:
Probably we've all seen a wedding reception, an event meant to be full of spontaneous expressions of joy, transformed by the photographer into a series of staged events. “Kiss the bride.” “Again, please.” “Cut a piece of the wedding cake.” “Each of you feed the other.” “All you spectators, move out of the way of the camera.” It is amazing how tolerant we have become of this manipulation of the experience: the act of recording taking precedence over the event.
Interesting side question: why do we want all these recordings? why do we cling so hard to keeping certain moments? Fairly certain this is a Deep Question. (or a question with a simple answer, but a difficult problem to solve.)
But look at Thad's devices vs. Glass. He's got a Twiddler one-handed keyboard, he's been taking notes and pulling things up on the fly for 20 years, he is an expert at wearable computing. If Glass becomes a mainstream thing, we'll run out to the Google Store and buy it to show off to our friends tomorrow. He's an experienced photographer with a DSLR; most of us will be chumps with point-and-shoots. (or, chumps with DSLRs, pretty much the same thing.) Which means we'll have obstructionist artifacts, not intensifying ones. And they'll be on our faces!
