Nostr provides an immutable set of novel incentives for developers and users. Which then provides an entirely new paradigm for development, UX and use cases.
It may be that these novel incentives create such an attractive environment for developers and users that what gets built on Nostr is objectively superior to all legacy products (eventually) and that creates a feedback that sees Nostr emerge as the protocol where the better apps exists interoperably.
I wouldn’t underestimate what can happen here in the next 10 years. Centralized products continue to regress and Nostr continues to evolve.
