Glass will be disruptive. I'm in the first set of users on it and it's impressive. I see a new class of services and products with not only the immediacy of the phone, but the power of first-person augmentation. Think of the possibilities! Developers can help people communicate better, know more, live healthier, become smarter, remember more, do more, record more, consume more, and so on and so on.
Glass entrepreneurs have a real opportunity to touch people's lives in a very intimate way. I think there is tremendous opportunity for companies that do this right.
