Part of our brand is that we're pretty understated in what we do. If you look at other technology companies, they might preannounce things, and it will be a couple years before they really happen, and they don't happen in the way they said they would.

For me, privacy and security are really important. We think about it in terms of both: You can't have privacy without security.

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.

We are excited about Internet access in general. With better access to the Internet, people do more searches.

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.

Lots of companies don't succeed over time. What do they fundamentally do wrong? They usually miss the future.

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.
