Video is growing very quickly on Facebook. A lot of people compare that to YouTube. I think that kind of makes sense. YouTube isn't the only video service, but I think it's the biggest, and it probably makes more sense to compare Facebook video to YouTube rather than Netflix because that's a completely different kind of content.

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

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.

There are really two core principles at play here. There's giving people a voice so that people can express their opinions. Then, there's keeping the community safe, which I think is really important. We're not gonna let people plan violence or attack each other or do bad things.

Just take terrorism, for example. We have a team of more than 200 people working on counterterrorism. I mean, that's pretty intense. That's not like what people think about what Facebook is.

Now the playbook is we build AI tools to go find these fake accounts, find coordinated networks of inauthentic activity, and take them down; we make it much harder for anyone to advertise in ways that they shouldn't be.
