I really think we need a monitored internet for under 13s. The internet is just to fucked up at the moment. I never thought I would be someone advocating for this because i grew up on the wild west internet watching people getting beheaded and stuff. But all that is nothing compared to being bombarded with friendly, trustworthy (seeming) people that constantly spread lies and misinformation that shapes your world view.
I dont know its a hard problem to solve. Above my paygrade thats for sure.
