The vision. Don't you see it? If we can pull this off, technology thereafter will be embedded into our consciousness. The reality, as we see it, will be transformed. We as human beings will literally become "supermen", in the sense that we will be able to "see" so much more than we could ever imagine. To an extent, this is a human evolution.
Dude I don't care what you think, but Google is the greatest technology organization ever existed. The "How It Feels" video literally made me in tears because the vision is so great, so compelling. The way we interact will change fundamentally, but that isn't a bad thing. People are always terrified by progress because progress means difference, and people feel comfort in falling back to the same thing. But, again, I don't care. The future is already here; it's just not evenly distributed. We will all be living in an age of augmented reality.
