I think that it is a definite maybe.

But it will have more of a struggle if the Apple app store and Google play store decide to blanket reject any new apps that are nostr related for whatever reason. It is already a pain for indie developers to get approved with normal user generated content. If nostr gets a few bad media stories regarding undesirable content, they could decide to crack down. And most people still depend on those app stores for apps.. and "the future of social media" probably depends on most people. I'm excited for nostr, though!
