I think you're right and I think it's strange that we focus so much on crypto and other high-tech solutions to problems we don't have, but not on federated distributed versions of social media, messaging, video hosting. I guess it's not as new and shiny.

I've been using matrix for the past year or so and I can tell you it's been great. I'm surprised at how stable and easy it is. I text friends who are on different servers, and no one notices. The clients are all starting to get E2EE by default. Hopefully the future is as warm.
