I just realized why wearable like Google Glass was such a big deal for Google. We human brain is constantly feeding in data and rationalizing objects we see, things we do. We are supervised as we grow and we continue to rationalize things on our own terms.<p>With wearable, if you allow the eyes of machines to read the world with you, hear your conversation, with enough time, your machine should be capable of learning enough to become like you. With millions of people doing so, you essentially create an AI that is like human able to answer complex questions.
