Everything has its limit - iron ore cannot be educated into gold.

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.

Over time I think we will probably see a closer merger of biological intelligence and digital 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.

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.

I'm a great believer that any tool that enhances communication has profound effects in terms of how people can learn from each other, and how they can achieve the kind of freedoms that they're interested in.
