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.

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.

Our mission is to organize the world's information. Clearly, the more information we have when we do a search, the better it's going to work.

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.

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.

Advances in the technology of telecommunications have proved an unambiguous threat to totalitarian regimes everywhere.
