It is the essence of innovation to fail most of the time.

I do believe that making a factory for innovation, a moon-shot factory, is possible.

The moonshot for Google Glass is to harmonize the physical and digital worlds. It is specifically to find a way to help people be naturally, elegantly situated, physical and digitally, at the same time.

Most of us have to spend a lot of energy to learn how to drive a car. Then we have to spend the rest of our lives over-concentrating as we drive and text and eat a burrito and put on makeup. As a result, 30,000 people die every year in a car accident in the U.S.

When you try to do something ten per cent better, you tend to work from where you are: if I ask you to make a car that goes 50 miles a gallon, you can just retool the engine you already have.

Glass is the world's worst spy camera. If you want to surreptitiously take photos, I would not use Glass.
