Back, you know, a few generations ago, people didn't have a way to share information and express their opinions efficiently to a lot of people. But now they do. Right now, with social networks and other tools on the Internet, all of these 500 million people have a way to say what they're thinking and have their voice be heard.

You can think about the metaverse as an embodied internet, where instead of just viewing content - you are in it. And you feel present with other people as if you were in other places, having different experiences that you couldn't necessarily do on a 2D app or webpage, like dancing, for example, or different types of fitness.

One of the things that I'm very mindful of is to make sure that the services that we're building help to create meaningful interactions between people and not just a place where people can zone out and consume content for a long time.

I mean, we've built a lot of products that we think are good, and will help people share photos and share videos and write messages to each other. But it's really all about how people are spreading Facebook around the world in all these different countries. And that's what's so amazing about the scale that it's at today.

So I think that the scale of the systems has created this responsibility for us, where we have to be more proactive about finding and addressing issues [harmful content]. And we can do that both by building technology that is possible now, but wasn't even possible five or ten years ago, and by hiring people at a scale that would not have been possible for us before.

Moderating content at scale is insane. 3.2 billion people use one of our services every day. It's wild.
