Small groups of people can have a really huge impact.

We really care about our brand. We really want it to stand for high quality. We want people to be excited about it, for it to be fun.

My job as a leader is to make sure everybody in the company has great opportunities, and that they feel they're having a meaningful impact and are contributing to the good of society. As a world, we're doing a better job of that. My goal is for Google to lead, not follow that.

If you can run the company a bit more collaboratively, you get a better result, because you have more bandwidth and checking and balancing going on.

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

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.

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