Optimism is important. You have to be a little silly about the goals you are going to set. There is a phrase I learned in college called, 'having a healthy disregard for the impossible.' That is a really good phrase. You should try to do things that most people would not do.

My grandfather was an autoworker, and I have a weapon he manufactured to protect himself from the company that he would carry to work. It's a big iron pipe with a hunk of lead on the head. I think about how far we've come as companies from those days, where workers had to protect themselves from the company.

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.

If your access to health care involves your leaving work and driving somewhere and parking and waiting for a long time, that's not going to promote healthiness.

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

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

We have a mantra: don't be evil, which is to do the best things we know how for our users, for our customers, for everyone. So I think if we were known for that, it would be a wonderful thing.
