Every business in the future, just like they have an email address, a website, and a social media presence today, is going to have an AI agent that their customers can talk to in the future.

I try to spend my time on areas that I think are important for the future, and where I think I can add value.

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.

Friends congratulate me after a quarterly-earnings announcement and say, 'Good job, great quarter '... And I'll say, 'Thank you, but that quarter was baked three years ago. I'm working on a quarter that'll happen in 2021 right now.'

Those quarterly results were fully baked three years ago. So today I'm working on a quarter that will happen in 2020, not next quarter. Next quarter is done already and it's probably been done for a couple years.

Patience and foresight are the two most important qualities in business.
