For the first time we're allowing developers who don't work at Facebook to develop applications just as if they were. That's a big deal because it means that all developers have a new way of doing business if they choose to take advantage of it. There are whole companies that are forming whose only product is a Facebook Platform application.

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

There are a few other things that I built when I was at Harvard that were kind of smaller versions of Facebook.

I literally coded Facebook in my dorm room and launched it from my dorm room. I rented a server for $85 a month, and I funded it by putting an ad on the side, and we've funded ever since by putting ads on the side.

Glance into the world just as though time were gone: and everything crooked will become straight to you.

AI is real and will change every industry. We are living in a golden age, and there is reason to be optimistic. There has never been a better time to be an entrepreneur and start a start-up.
