Welcome to the Idiocracy!
We have laws for protecting kids from using guns, smoking, drinking, it's only the ubiquitous availability of access to the internet that's the problem. The internet, as we all know, is basically a giant network and nothing more, where it went wrong is how easy we made it for people to slap a big pile of shit on top of that network.
Social media is mostly a bullshit cesspit of crap hosted by tedious narcissists constantly boasting about how great they are and expecting every else to worship them, even sending them money. We used to scoff at idiots sending money to TV evangelists back in the 1990s now some 15 year old girl sits with here cleavage on display, playing video games and a bunch of dribbling morons send her disgusting suggestions and offer money if she'll do them. That's just the stuff like Twitch streaming that's easy to find, let's no even get into the seedier side of OnlyFans and other awful locations out there.
Next we have the basically mind bending cults like Facebook , TikTok and Instagram where they pride themselves on how addictive their algorithms make people to their services. Take a trip on public transport these days and 80% of the people around you will be sitting there like zombies "doom scrolling" their phones to kingdom come, empty vacuous eyes just looking to keep those dopamine levels up enough so they can cope with their own boring, shit lives, thinking that seeing one more video or pic of a smiling big-titted/muscled moron outside a mansion will make them happy as they can dream that's what they'll have one day if they wish hard enough.
When we have kids of 8 out there who want to be an "internet influencer" when they grow up, humanity has lost the plot.
