We know that Google Earth and Google Maps have had a tremendous impact on Google traffic, users, brand, adoption, and advertisers. We also know Google News, for example, which we don't monetize, has had a tremendous impact on searches and on query quality. We know those people search more. Because we've measured it.

People are surprised to find out that an awful lot of people think that they're idiots.

Half of Google's revenue comes from selling text-based ads that are placed near search results and are related to the topic of the search. Another half of its revenues come from licensing its search technology to companies like Yahoo.

Technology will move faster than governments, so don't legislate before you understand the consequences.

It's very difficult for governments to dominate the Internet because it's so difficult to control. People want to be free. People want to hear multiple voices. They want to make their own decisions. And people who see things will report things.

I worry that the level of interrupt, the sort of overwhelming rapidity of information — and especially of stressful information — is in fact affecting cognition. It is in fact affecting deeper thinking. I still believe that sitting down and reading a book is the best way to really learn something.
 And I worry that we’re losing that.

Google docs and spreadsheets don't work if you're on an airplane. But it's a technical problem that is going to get solved. Eventually you will be able to work on a plane as if you are connected and, then when you get reconnected to the Internet, your computer will just synchronize with the cloud.
