How exciting is it to come to work if the best you can do is trounce some other company that does roughly the same thing?

The "Be good" concept also comes up when we design our products. We want them to have positive social effects.

We are excited about Internet access in general. With better access to the Internet, people do more searches.

For me, privacy and security are really important. We think about it in terms of both: You can't have privacy without security.

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.

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.

One of our big goals in search is to make search that really understands exactly what you want, understands everything in the world. As computer scientists, we call that artificial intelligence.
