Artificial intelligence would be the ultimate version of Google. The ultimate search engine that would understand everything on the Web. It would understand exactly what you wanted, and it would give you the right thing. We're nowhere near doing that now. However, we can get incrementally closer to that, and that is basically what we work on.

Basically, our goal is to organize the world's information and to make it universally accessible and useful.

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.

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.

It's very hard to fail completely, if you aim high enough.

As we transition from one screen to multiscreens, Google has enormous opportunities to innovate and drive ever higher monetization. Just like Search in 2000.

Small groups of people can have a really huge impact.
