Facebook is inherently viral.

AI systems will enable doctors to diagnose diseases and treat people better, so blocking that progress is probably one of the worst things you can do for making the world better.

Simply put: we don't build services to make money; we make money to build better services.

It only took me two weeks to build the first version of Facebook because I had so much stuff before then.

In the olden times, privacy was good. Today people want to share, people are more open.

Facebook was not originally created to be a company. It was built to accomplish a social mission - to make the world more open and connected.

I think that people just have this core desire to express who they are. And I think that's always existed.
