The problem is that people seek strong emotional reactions in a world that bores them with jobs they don't enjoy. It's what makes them want to use social media. For excitement. You are right tho, its not healthy. I don't think nostr will solve it. I just saw a post on here saying how great it could be to have AI serve us recommendations based on interests and past posts. But if what interests us is emotioanl reactions the AI will figure that out and serve us those. I think thats how facebook / twitter already work.
