I think as we all work to learn and navigate the future towards a world where AI fulfills its promise, the best way to do that is to work together and to share information and learn together. It'll speed up our ability to get ahead of this so that we can do a better job of setting our associates up for success.

So I guess I'm just very worried that with Internet privacy, we're doing the same thing we're doing with medical records, is we're throwing out the baby with the bathwater, and we're not really thinking about the tremendous good that can come from people sharing information with the right people in the right ways.

I think the main thing that we need to do is just provide people choice, show them what data's being collected -- search history, location data. We're excited about incognito mode in Chrome, and doing that in more ways, just giving people more choice and more awareness of what's going on.

You carry a phone. It knows where you are. There's so much more information about you, and that's an important thing, and it makes sense why people are asking difficult questions.

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

At Facebook, we're inspired by technologies that have revolutionized how people spread and consume information. We often talk about inventions like the printing press and the television - by simply making communication more efficient, they led to a complete transformation of many important parts of society. They gave more people a voice. They encouraged progress. They changed the way society was organized. They brought us closer together.
