So the idea that people wearing Glass are assholes is a ridiculous notion because there are already numerous ways to record someone without explicit approval, you already have the right to record anyone in a public place even without explicit permission, and it's already possible (and already happens) with existing smartphones. So if you're getting mad at Glass wearers for something that people are already doing, you're the asshole. The only difference between Glass and other technology is that Glass is newer and less common. That's it.
