I know it's unpopular and seen as anti free speech but I honestly think social media has such a detrimental effect in society, especially for children and mentally ill adults. I think there could be some type of restriction like, you can't use social media until you pass a certain age or life milestone. Maybe something like until you get your first job post university. If you aren't mentally proficient then you shouldn't be able to post online.Also If you don't have experience in a field you shouldn't be able to make YouTube videos or TikToks about the subject. Additionally id be in favor of certain apps being unavailable full stop for people under 18, or at the very least there being time limits set by the government for amount of time children can use it.
Obviously I understand this sort of thing could be a slippery slope and there would ideally need to be some sort of consensus from the people on what restrictions would be a net good but I get do tired of seeing blatant misinformation on social media be allowed and children's minds rotting from the slop that dominates the algorithm.
