The old school hacker crowd is so blind-rage anti-cryptocurrency they're letting pretty great novel things like Nostr and Farcaster fly under their radar. If they tried to mimic these designs you'd end up with worse cryptography (because all the new interesting stuff is mostly related to cryptocurrency) and would probably look like PGP + key servers. They'll make an excuse to put up with the status quo and live with it.

Both Nostr and Farcaster have weaknesses in their design but they do provide a good foundation for decentralized social media that could survive longer term without your content disappearing off the internet permanently. It's just a hard pill for some people to swallow because the design breaks from tradition.

I predict ActivityPub will exist in some form for a long time but there will be a lot of data lost over the years. It's already happening.
