Why isn't the discussion more about general ban of cancerous social medias for people who are not yet mentally developed and fall ridiculously easily into proper addiction for it? It would be wonderful if state/society protected vulnerable, but when thats not the case its each parent's responsibility. The hell will freeze sooner than I will allow any form of this for my kids below maybe 15 years old. Its so sad to see rather small kids glued to screens, parents by their negligence and laziness fucking up their most important people in their lives, for life. Where is the threshold just that they can get a bit more time off from parental duties to slouch on couch, meth or crack? Or course I don't expect miracles from adults who are themselves deep in addictive behaviors themselves, then its just a sad story all the way down the line. Children need tons of time off any screen for proper development, not just early years. Social skills, anxiety, self worth, mental stability and resilience. None of this happens in front of screen, in contrary a lot of harm in not only these areas are very frequent. Very happy to be part of society (Switzerland) where similar values are shared by most peers around us and also whole public education system.
