I honestly don't believe that social networks bring us closer together. They can, but in practice they don't. Instead I believe they give us the illusion of feeling closer and more involved, but that is likely cognitive dissonance (akin to thinking ChatGPT is smart because it speaks). The only way to build relationships is through shared experiences. This can be done online btw, but these experiences are not doing things like liking peoples posts or occasionally commenting in threads. They involved personal and/or group conversations/activities. That's why you're more likely to find friends playing videogames online than through a social network (assuming pure online).
