You need to get one thing done well, or else you don't have permission to do anything else.

Over time, it's becoming more and more understood by people that we're acting in their interests. And that's a very, very powerful thing for our brand.

Our mission is to organize the world's information. Clearly, the more information we have when we do a search, the better it's going to work.

I like going to Burning Man, for example. That's an environment where people can try out different things. I think as technologists we should have some safe places where we can try out some new things and figure out what is the effect on society, what's the effect on people, without having to deploy kind of into the normal world.

Optimism is important. You have to be a little silly about the goals you are going to set. There is a phrase I learned in college called, 'having a healthy disregard for the impossible.' That is a really good phrase. You should try to do things that most people would not do.

Artificial intelligence would be the ultimate version of Google. The ultimate search engine that would understand everything on the Web. It would understand exactly what you wanted, and it would give you the right thing. We're nowhere near doing that now. However, we can get incrementally closer to that, and that is basically what we work on.

Lots of companies don’t succeed over time. What do they fundamentally do wrong? They usually miss the future. I try to focus on that: What is the future really going to be? And how do we create it? And how do we power our organization to really focus on that and really drive it at a high rate? When I was working on Android, I felt guilty. It wasn’t what we were working on, it was a start-up, and I felt guilty. That was stupid! It was the future.
