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.

You can make money without doing evil.

The kind of environment that we developed Google in, the reason that we were able to develop a search engine, is the web was so open. Once you get too many rules, that will stifle innovation.

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. I was getting lost at our site keeping track of everything. I would rather have a smaller set of products that have a shared set of features.

It's a romantic notion that you're going to have one brilliant idea and then everything is going to be great... but the execution and delivery are what's key.

I am sometimes something of a lazy person, so when I end up spending a lot of time using something myself - as I did with Google in the earliest of days, I knew it was a big deal.

Solving big problems is easier than solving little problems.
