The Web is a vast collection of completely uncontrolled heterogeneous documents.

For a lot of companies, it's useful for them to feel like they have an obvious competitor and to rally around that. I personally believe it's better to shoot higher. You don't want to be looking at your competitors. You want to be looking at what's possible and how to make the world better.

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.

We have always wanted Google to be a company that is deserving of great love. But we recognize this is an ambitious goal because most large companies are not well-loved, or even seemingly set up with that in mind. We're lucky to have a very direct relationship with our users, which creates a strong incentive for us to do the right thing .

You may think using Google's great, but I still think it's terrible.

You're probably on the right track if you feel like a sidewalk worm during a rainstorm.

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.
