And then we got really good at dialing in internationalization and helping the service grow in different countries.

And that was like a whole competence that we needed to develop.

And...

and helping people basically spread the service to their friends.

That was one of the things, once we got very good at that, that was one of the things that made me feel like, hey, if Instagram joined us early on, then I felt like we could help grow that quickly.

And same with WhatsApp.

And I think that that's sort of been a core competence that we've developed and been able to execute on.

And others have too, right?

I mean, ByteDance obviously have done a very good job with TikTok and have reached more than a billion people there.

But it's certainly not automatic, right?

I think you need a certain level of execution to basically get there.

And I think for whatever reason, I think Twitter has this great idea and sort of magic in the service, but they just haven't kind of cracked that piece yet.

And I think that that's made it so that you're seeing all these other things, whether it's Mastodon or...

um or or blue sky um that that i think are you know maybe just different different cuts of the same thing but you know i think through the last generation of of um social media overall one of the interesting experiments that i think should get run at larger scale is what happens if there's somewhat more decentralized control and if it's like the stack is more open throughout and um i've just been pretty fascinated by that and seeing how that works um

To some degree, end-to-end encryption on WhatsApp and as we bring it to other services provides an element of it because it pushes the service really out to the edges.

I mean, the server part of this that we run for WhatsApp is relatively very thin compared to what we do on Facebook or Instagram.

And much more of the complexity is in how the apps kind of negotiate with each other to pass information in a fully end-to-end encrypted way.

But I don't know.

I think that that is a good model.

I think it puts more power in individuals' hands, and there are a lot of benefits of it if you can make it happen.
