It won't be long before the Google Glass tech will be put into glasses that don't look obvious and a little ridiculous. For those of you who think you're always going to be able to tell who's recording video of you with wearable Google Glass tech: think again.
Right now they look like "nerds" and "geeks" according to the people who are angry about losing their privacy (or who can't afford them). Pretty soon, they'll look like anyone with eyeglasses. I've seen people here talk about punching anyone they see wearing Google Glass looking at them. What are you going to do when this technology is so ubiquitous that anyone with glasses might be recording you?
Maybe the best we can hope for is that the tech is so widely-available, and moddable, that it's a level playing field (a very exposed playing field). But like it or not, it's coming.
