There are many machines throughout history that were built to do something better than a human can.

Building a mission and building a business go hand-in-hand. It is true that the primary thing that makes me excited about what we're doing is the mission, but I also think, from the very beginning, we've had this healthy understanding which is that we need to do both.

It took 10 years to go from building the initial Smartphone to reaching the mass market. BlackBerry came out in 2003 and it didn't get to about a billion units until 2013. So I can't imagine it would be much faster for VR.

I think there's confusion around what the point of social networks is. A lot of different companies characterized as social networks have different goals - some serve the function of business networking, some are media portals. What we're trying to do is just make it really efficient for people to communicate, get information and share information.

Our mission is to make the world more open and connected. We do this by giving people the power to share whatever they want and be connected to whoever they want, no matter where they are.

A lot of the time the experts, the people who are supposed to be able to tell you what to do, will tell you that you can't do something even when you know you can. And a lot of the time it's your friends ... who tell you you can do it.

There is something wrong with our system when I can leave here and make billions of dollars in 10 years while millions of students can't even afford to pay off their loans, let alone start a business. We all know you don't get successful just by having a good idea or working hard. You get successful by being lucky too. If I had to support my family growing up, instead of having the time to learn how to code. If I didn't know that I was gonna be fine if Facebook didn't work out, then I wouldn't be standing up here today. And if we're honest, we all know how much luck we've had.
