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.

Small groups of people can have a really huge impact.

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.

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

Part of our brand is that we're pretty understated in what we do. If you look at other technology companies, they might preannounce things, and it will be a couple years before they really happen, and they don't happen in the way they said they would.

If your business is static, you're likely to have issues.

How exciting is it to come to work if the best you can do is trounce some other company that does roughly the same thing?
