The ultimate search engine... would understand exactly what you mean and give back exactly what you want.

We understand the need to balance our short- and longer-term needs because our revenue is the engine that funds all our innovation. But over time, our emerging high-usage products will likely generate significant new revenue streams for Google as well as for our partners, just as search does today.

Technology should do the hard work, so you can get on and live your life. We're only at one percent of what's possible, and we're moving slow relative to the opportunity we have.

We believe strongly that in the long term, we will be better served - as shareholders and in all other ways - by a company that does good things for the world even if we forgo some short term gains. This is an important aspect of our culture and is broadly shared within the company.

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.

I have a simple algorithm, which is, wherever you see paid researchers instead of grad students, that's not where you want to be doing research.
