In late 1995, I started collecting the links on the Web, because my advisor and I decided that would be a good thing to do. We didn't know exactly what I was going to do with it, but it seemed like no one was really looking at the links on the Web - which pages link to which pages.

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."

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.

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