Computing is kind of a mess. Your computer doesn't know where you are. It doesn't know what you're doing. It doesn't know what you know.

If you look at the people who have high impact, they have pretty general knowledge. They don't have a really narrowly focused education.

If you're changing the world, you're working on important things. You're excited to get up in the morning.

Most of us carry at least one device, all the time, every day. In fact many of us would feel naked without our smartphone. It's hardly surprising mobile search queries - and mobile commerce - are growing dramatically across the world.

Basically, our goal is to organize the world's information and to make it universally accessible and useful.

We have a mantra: don't be evil, which is to do the best things we know how for our users, for our customers, for everyone. So I think if we were known for that, it would be a wonderful thing.

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