That said, with bans upcoming or in force in a lot places, what measures should we monitor to see improvements in wellbeing etc. (screen time isn't one there, I'd say)? What do we do if those do not go up noticably?
Social Media allowed ordinary people to challenge on a global scale the oficially-sanctioned narrative. A generation has already grown with full distrust on what they learn from traditional media.
With that picture, addressing the (undeniable) negative effects of Social Media is only the sales pitch for introducing new legislation. The true goal of the legislation however is not to "save the children", but rather to ensure that the next generations will be obedient and meek.
Hasn't been true for a while. Now it grants people with money and state actors unprecedented control over what ordinary people are allowed to see and mold them to desired narratives.
But it's obvious that social media also still allows grassroots action and organization in ways that simply weren't possible under old media. We need to be careful when talking about regulating or banning social media outright that we don't throw the baby out with the bathwater - we will be losing freedoms when we lose it and centralizing control of media and communication with governments and corporations (even more so than with the big social media silos now.) And freedoms lost aren't easily gained back.
Then again, as I’m writing this, how much of that was due to manipulation and promotion by adversarial powers… almost nothing is truly organic anymore, or at least you can’t tell if it is, and I suppose that’s what you’re getting at.
Yes, but over time, even pre-Internet generations have learned to be skeptical of everything watched or read online. Children growing up in this environment will almost certainly adapt and learn to do the same.
So, at best, laws restricting Social Media are a nanny state overreach, and at worst dystopian Big-Brother-style narrative control.
We have witnessed a similar overreach in the distant past with printing-press regulation laws [1]. But at the time, they power structure was different so they could instate an outright ban without hiding behind "think of the children" or the Red Scare.
