Artificial intelligence would be the ultimate version of Google.

As we transition from one screen to multiscreens, Google has enormous opportunities to innovate and drive ever higher monetization. Just like Search in 2000.

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.

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."

Our mission is to organize the world's information. Clearly, the more information we have when we do a search, the better it's going to work.

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.
