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.

When it’s too easy to get money, then you get a lot of noise mixed in with the real innovation and entrepreneurship. Tough times bring out the best parts of Silicon Valley.

We've seen a massive attack on the freedom of the web. Governments are realizing the power of this medium to organize people and they are trying to clamp down across the world, not just in places like China and North Korea; we're seeing bills in the United States, in Italy, all across the world.

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.

But the vast majority of books ever written are not accessible to anyone except the most tenacious researchers at premier academic libraries. Books written after 1923 quickly disappear into a literary black hole.

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.

I am sometimes something of a lazy person, so when I end up spending a lot of time using something myself - as I did with Google in the earliest of days, I knew it was a big deal.
