#ditto is next gen because it's not relay only. So it has a chance of scaling. It has an architecture, Alex has provably scaled things in the past, too. So we know it can be done. My preferred stack is what I am calling #SAND -- Solid, ActivityPub, Nostr, Ditto. I think the future is agentic, ie agents are the new apps. And they can communicate over nostr, too.
