guelo: Google Glass isn't about making movies per se but about sharing personal experiences -- live and otherwise. Think about it for a moment and you'll get it.
Not really that much different to recording Video with a Smartphone.
I get that there is a difference in that you are always wearing it and are theoretically always on, and photos/vids of Smartphones are huge, but … seriously … how many experiences of your personal day today would you like to share? Nah.
On the other side there are certainly people who are burning to attention whoring the shit out of Google Glasses. Perhaps it would be like a more extreme version of Twitter were 99% of people are following a very vocal 1% minority. And if Sergey Brin would publicly stream his Glass video I would watch it and place the video in a corner of my desktop screen. It would be like having a pet or the first Justin.tv all over again.
What was that website a few years back where these guys wandered the streets of Manhattan with a live camera strapped to them, and you could send them suggestions for improv-like interactions with the passerby? It was a lot of fun, really.
EDIT- "Mod My Life". Maybe that's an idea whose time has come.
