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.

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.

About half my time is spent on business operation type stuff.

I think a simple rule of business is, if you do the things that are easier first, then you can actually make a lot of progress.

Retail is detail, and that plays out throughout the international business as well. Today's portfolio has got omnichannel businesses in Mexico, Central America, Canada, China, but we also have an e-commerce marketplace in India with Flipkart and our financial services business in India, PhonePe - those are a bit different, but the other markets have a lot of commonality strategically.

A business that makes nothing but money is a poor business.
