I don't disagree. But like Facebook, what it will take is an abuse of the technology. Once people find that they are appearing on the internet in snapchats taken with these glasses without being aware it was happening, then there will be some backlash. In the end, those people in the theater still carry their phones, but they have learned to use them more responsibly. The cameras aren't going away, nor should they. But like any bad actor, someone who wants to capture video of someone else without their knowledge has many ways of doing it now, and nothing will change that, even banning all devices with cameras, everywhere -- which is never going to happen anyway.
