sure, there would be absolutely no reason to ban kids from social media in a utopic society where people treated each other with respect , were all as educated as the average hacker news inhabitant , and behaved rationally. meanwhile in reality, modern social media have nothing to do with socialization and everything to do with abusing brains to maximise engagement. while this point is n=1, it really does not take more than a few minutes for short form content to crash my motivation, so i completely disagree with your 'several hours' figure.

fuck it, ban kids from having any form of smart phone or social media. give em all sony ericssons with pre paid sims that force them to put effort into their texts and actually socialize. maybe that will give imagination a fighting chance. what possible benefit could there be to let kids doom scroll? if you were a kid, why would you read or play or socialize when you could doom scroll? yes it is a parents responsibility to control their kids, and not one parent has any idea or education as to how modern social media affects a child - do you expect modern parents to spontaneously manifest this knowledge?

for what its worth , i once suggested to simply make it illegal for parents to let kids on facebook. but that doesn't offer much scope for multi national corporations to scrape PII (which is probably the real priority)
