I don't see these two futures as necessarily incompatible, and could certainly use more time alone in cabins. But sometimes it's better to both relax and be productive with other people, and technology is good for removing the constraint that those people be in the same place. Maybe Glass won't be a device on which we receive minute social updates, but it can still be useful for the same reasons a telephone is useful. Maybe it could even have a similar busy signal, so you're not interrupted if you're already talking to someone.

I think the 'worth' of a picture depends on the circumstances – people take many more pictures than they did twenty years ago, now that we don't need to get the film developed – and a further simplification of the process might lower the threshold further. A pretty sunset is a pretty sunset, but the pretty sunset from someone you love halfway around the world is something different. An interesting thing about Glass is that it minimizes the duration of the interruption needed to both send and receive that sunset.
