I think people tend to be worried about every new technology that comes along.

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

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.

This is a perverse thing, personally, but I would rather be in the cycle where people are underestimating us. It gives us latitude to go out and make big bets that excite and amaze people.

And connected is helping people stay in touch and maintain empathy for each other, and bandwidth.

Connecting the world is really important, and that is something that we want to do. That is why Facebook is here on this planet.

We want Facebook to be one of the best places people can go to learn how to build stuff.
