No I get that, but this is different honestly. Look up rates of teenage depression/anxiety/suicide attempts, it's a stunning correlation with the advent of smartphones and social media. Millenials got out just in time.
I agree there are still a lot of problems with social media, not the least of which is I'm not sure if yt or fb ever adjusted their algos to not immediately start pushing alt right and neo nazi content. But don't forget that the suicide rates are also correlated with a bunch of other bad shit, like growing income inequality and healthcare spending, loss of 3rd places, rent hikes, etc.
I think it has a lot more to do with social media than smart phones. I remember kids being bullied through tombstone messages on Oregon Trail floppies.
