Servers, protocols, APis, it will all come and go, identity is the only thing that we can salvage and maintain our if that ship of theseus, which is why it breaks my heart when people bake identity in the transports and protocols, when the very internet proves that Name systems are wholly separate layer, in fact it is the most durable and orthogonal layer ever, it will probably outlast even IP if we ever made something that overcomes IP. Let's solve identity, at protocol and UX level, then figure out the rest as we go. If you really need broadcasting, well Nostr is here, broadcast if you must, if you need reliable messaging Email is still here mail as you wish... But don't make Email accounts identities, and don't make Nostr keys identities either.
