Google will fulfill its mission only when its search engine is AI-complete. You guys know what that means? That's artificial intelligence.

Stanford would be first. You can take universities and just rank them, and they come out in the order you'd expect. So we thought, "This is really interesting. This thing really works. We should use it for search." So I started building a search engine.

In technology, we need revolutionary change, not incremental change.

We want to build technology that everybody loves using, and that affects everyone. We want to create beautiful, intuitive services and technologies that are so incredibly useful that people use them twice a day. Like they use a toothbrush. There aren't that many things people use twice a day.

Artificial intelligence would be the ultimate version of Google.

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.
