On the same subject, and based on the reality of today's largely digital dating market, wouldn't it be a good idea to have a NOSTR-based dating app? I'm not claiming that this alone will solve the birth rate problem, but today dating apps are, it seems to me, the mobile apps that generate the most revenue. The fiat mentality is omnipresent in the leaders of this market, we know how their business model works and it's completely abject. Today, these apps are for many the only way to get in touch with a potential partner, and that's not likely to change.
If the algorithm were optimized to maximize encounters leading to quality relationships rather than frustrating young men into paying a subscription fee, it could have a real impact on people's behavior and the birth rate.
But same problem as with Bitcoin, it takes adoption, and I can't see how an ideal NOSTR dating app would attract girls on it.
