As a precaution, we’re making machines extremely heavy with very tiny legs.

My job as a leader is to make sure everybody in the company has great opportunities, and that they feel they're having a meaningful impact and are contributing to the good of society. As a world, we're doing a better job of that. My goal is for Google to lead, not follow that.

We have always tried to concentrate on the long term, and to place bets on technology we believe will have a significant impact over time. It's hard to imagine now, but when we started Google most people thought search was a solved problem and that there was no money to be made apart from some banner advertising. We felt the exact opposite: that search quality was very poor, and that awesome user experiences would clearly make money.

I have over 2 million followers now on Google Plus.

Big companies have always needed and cooperated in areas where it made sense.

You don't need to have a 100-person company to develop that idea.

Over time, it's becoming more and more understood by people that we're acting in their interests. And that's a very, very powerful thing for our brand.
