My vision when we started Google 15 years ago was that eventually you wouldn't have to have a search query at all. You'd just have information come to you as you needed it. And Google Glass is now, 15 years later, sort of the first form factor that I think can deliver that vision.

It's important not to overstate the benefits of ideas. Quite frankly, I know it's kind of a romantic notion that you're just going to have this one brilliant idea and then everything is going to be great. But the fact is that coming up with an idea is the least important part of creating something great. It has to be the right idea and have good taste, but the execution and delivery are what's key.

We are focused on features, not products. We eliminated future products that would have made the complexity problem worse. We don't want to have 20 different products that work in 20 different ways.
