It's not enough not to be evil. We also actively try to be good.

My vision when we started Google 15 years ago was that eventually you wouldn't have to have a search query at all. You'd just have information come to you as you needed it. And Google Glass is now, 15 years later, sort of the first form factor that I think can deliver that vision.

Obviously everyone wants to be successful, but I want to be looked back on as being very innovative, very trusted and ethical and ultimately making a big difference in the world.

Generally, health is just so heavily regulated. It's just a painful business to be in. It's just not necessarily how I want to spend my time.

As we go forward, I hope we're going to continue to use technology to make really big differences in how people live and work.

The kind of environment that we developed Google in, the reason that we were able to develop a search engine, is the web was so open. Once you get too many rules, that will stifle innovation.

In the future, search engines should be as useful as HAL in the movie 2001: A Space Odyssey-but hopefully they won't kill people.
