It really matters whether people are working on generating clean energy or improving transportation or making the Internet work better and all those things. And small groups of people can have a really huge impact.

We're at maybe 1% of what is possible. Despite the faster change, we're still moving slow relative to the opportunities we have. I think a lot of that is because of the negativity... Every story I read is Google vs someone else. That's boring. We should be focusing on building the things that don't exist.

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.

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