Nostr is a subset of http.  That means that everything nostr can do, http can do.  We just didnt realize it.  That's good news, because http has scaled to 5.3 billion people.  Whereas nostr is stable at 50k users.  All you need to do take what you learnt on nostr, not be solely dependent on relays, and bring your apps to the other 5 billion people.
