For me, privacy and security are really important. We think about it in terms of both: You can't have privacy without security.

Excellence matters, and technology advances so fast that the potential for improvement is tremendous. So, since becoming CEO again, I've pushed hard to increase our velocity, improve our execution, and focus on the big bets that will make a difference in the world.

Google will fulfill its mission only when its search engine is AI-complete. You guys know what that means? That's artificial intelligence.

There are basically no companies that have good slow decisions. There are only companies that have good fast decisions.

The "Be good" concept also comes up when we design our products. We want them to have positive social effects.

Our goal is long-term growth in revenue and absolute profit - so we invest aggressively in future innovation while tightly managing our short-term costs.

I feel like my job as CEO is always to be pushing people ahead.
