You need to invent things and you need to get them to people. You need to commercialize those inventions. Obviously, the best way we've come up with doing that is through companies.

You may think using Google's great, but I still think it's terrible.

Artificial intelligence would be the ultimate version of Google. The ultimate search engine that would understand everything on the Web. It would understand exactly what you wanted, and it would give you the right thing. We're nowhere near doing that now. However, we can get incrementally closer to that, and that is basically what we work on.

The "Be good" concept also comes up when we design our products. We want them to have positive social effects.

Especially in technology, we need revolutionary change, not incremental change.
