This is really fascinating to me. It would be interesting to see each country set up their own Mastodon/Lemmy/Kbin/other federated systems and have those instances constantly talk to each other. Like others have commented, It seems like a great way to keep the communication style and interaction of twitter/facebook, while also protecting the validity of the information through private instances. Really smart decision.
A little intimidating at first but after finding a decent mobile app (connect) and following a few communities I think I'm getting it. The whole federation and indexing is really interesting to me and eventually I could see myself hosting a small instance.
Your phone does the same thing just without communicating it. Samsung phones let you change the percentage of the battery is "100%" charged.
