There are a whole bunch of people who don't like to shop. But there are also people, maybe, who even do like to shop but are very time pressured. And so shopping online can save people time.

The Internet is disrupting every media industry...people can complain about that, but complaining is not a strategy. And Amazon is not happening to book selling, the future is happening to book selling.

So I guess I'm just very worried that with Internet privacy, we're doing the same thing we're doing with medical records, is we're throwing out the baby with the bathwater, and we're not really thinking about the tremendous good that can come from people sharing information with the right people in the right ways.

People are mistaken when they think that technology just automatically improves. It does not automatically improve. It only improves if a lot of people work very hard to make it better, and actually it will, I think, by itself degrade, actually. You look at great civilizations like Ancient Egypt, and they were able to make the pyramids, and they forgot how to do that. And then the Romans, they built these incredible aqueducts. They forgot how to do it.

I think the main thing that we need to do is just provide people choice, show them what data's being collected -- search history, location data. We're excited about incognito mode in Chrome, and doing that in more ways, just giving people more choice and more awareness of what's going on.

Search engines didn't really understand the notion of which pages were more important. If you typed "Stanford," you got random pages that mentioned Stanford. This obviously wasn't going to work.
