Seems to me anyway it's not nostr that matters, its the idea of an open protocol for social media per se. This is a difference to bitcoin, which really has to succeed because you couldn't plausibly launch / bootstrap an alternative decentralized money now - it's a one-shot game. But it doesn't matter if nostr is superceded by some other open protocol. As long as something exists with those properties all the free world will inevitably end up using it. (Though it would be nice if the entirety of future human discourse would turn out to originate from a bunch of shitposting btc maxis 😂)
