I agree with you about the harms social media causes. It's not helping matters at all, and actively harms people. But so does alcohol. Drinking can relax people, make them feel numb and happy for a short while. Doesn't help them at all. But we don't point the finger at alcohol, we say it's a symptom of a larger problem. In this case I'm saying social media consumption is the same, just a symptom of a larger problem.
And like alcohol, it doesn't actually help at all. It just takes a person's mind off their problems for a while. It lets them unplug and just mindlessly scroll Tiktok or Instagram. Say stupid shit on Twitter.
Building community is an answer to this problem. Arguing on the internet is like yelling at the void, where speaking in person tends to make someone think more and be more mindful of what they say, since the repercussions are immediate and right on front of you. And it's just better for the person too, getting to feel that connection to other people.
The problem though, is that it takes a lot more effort, time, and money to participate in community. The people I'm talking about, simply can't. They don't have that time, energy, or money. They can't afford to meet friends for dinner, even at each other's homes. They can't go meet friends at a nearby park because they're exhausted from work. They can't go hang out at a friend's place because of the time commitment. The couple of hours they might have at the end of the day is spent browsing simply because it's low energy and doesn't cost them anything more. It's the only thing that lets them unwind, or unplug, or blow off some steam.
I think the answer is to have the community meet these people where they are. That's a huge undertaking though, which is probably why we haven't seen very much of it yet. But it's going to be sorely needed.
