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.

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

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.

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

You may think using Google's great, but I still think it's terrible.

The ultimate search engine would basically understand everything in the world, and it would always give you the right thing. And we're a long, long ways from that.

Many leaders of big organizations, I think, don't believe that change is possible. But if you look at history, things do change, and if your business is static, you're likely to have issues.
