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

Sergey also came on very early, probably in late '95 or early '96, and was really interested in the data mining part. Basically, we thought, "Oh, we should be able to make a better search engine."

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.

Artificial intelligence would be the ultimate version of Google.

I think it sounds stupid if you have this big company, and you can only do five things. I think it's also not very good for the employees. Because then, you have 30,000 employees and they're all doing the same thing, which isn't very exciting for them.

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.
