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

Virtual Reality is really a new communication platform. By feeling truly present, you can share unbounded spaces and experiences with the people in your life. Imagine sharing not just moments with your friends online, but entire experiences and adventures.

Whenever I go to a new city, in order to help get on the right time zone and actually get a chance to see that city, I like running.

The biggest risk is not taking any risk... In a world that changing really quickly, the only strategy that is guaranteed to fail is not taking risks.

It used to be the case, like, you'd switch jobs, and then maybe you wouldn't keep in touch with all the people that you knew from that old job. Just because it was too hard. But one of the things that Facebook does is it makes it really easy to just stay in touch with all these people.

So many businesses get worried about looking like they might make a mistake, they become afraid to take any risk.

The thing I really care about is the mission, making the world open.
