I don't think the former scales, whereas the latter lends itself to amplification. Authenticity and community require much more complexity to uphold than anger, anxiety, and resentment.

I do take your point, and think that un-nuanced conversations about the evils of Social Media are unhelpful, but I think the scaling problem is the real danger. Negativity scales globally, positive sentiment and experience is limited to the individual or local level.

What do you think of any of this?

Probably, but because of salience asymmetry, we don't realise it. Like the good stuff is often more local as you say, and more distributed, while the bad stuff makes the news.
