The future is self hosted private invite only communities of vetted real life humans, likely done in person.
That's pretty much the present today. Tbh I'm fine with the public internet just dying off at this point and people going back to their local smaller scale groups.
And when you need longer reach than that?
A “I vouch for this person” system?
no, its public federated social media running on at protocol. no big tech control, no crypto bullshit like nostr, no way for bad admins to delete your posts like mastodon (they can only ban you from their own server). you can build a web of trust or vetting system on top of that like what tangled is doing for code.
