IMHO, social media itself is not the issue. The issue is rather, why are teenagers glued to their screens? The answer is because they aren't doing something else that is social and physical. So if you ban their access to TikTok or whatever, they are still stuck at home, bored and glued to their screen. Other online entertainment will capture their focus. Before you know it you'll end up trying to ban the whole intern…
I think many people on HN grew up glued to an internet that wasn't trying to intellectually molest them for capitalist and political gains.
This social media ban looks very reminiscent and I think it is all about creating a surveillance state, controlling the population to only see images and video in a centrally approved way.
