I am also going to say that nostr has all these things in some alpha form or another. However, it is very much a mess right now and it is harder IMHO to connect with others or curate my feed with stuff I like.
The advantage of small groups and fedi is starting with a small network and growing it slowly, this is more rewarding than starting with the whole world and trying to pull back.
Nostr might have all the features but its a mess right now
I'm not sure what the big deal is here. The US military has had swarm tech like this for almost a decade through DARPA performing mapping and scouting missions
