I don't necessarily disagree that phones might be harmful for kids' development.

I just don't know if they're nearly as harmful as say, repeated covid infections, a collapsing biosphere, a justifiably bleak vision of their future, or even a prevalent lack of agency, independence, and spaces for socialisation.

I'd focus on those first. Then phones.

"WE NEED TO PROTECT THE BRAINS OF OUR PRECIOUS CHILDREN!"

-By making it so they don't repeatedly catch a neurologically damaging infection twice a year by just attending school?

"LOL NO. IT'S THE PHONES, OBVIOUSLY! TAKE THEM AWAY!"

that's a false dichotomy, I'm afraid

as much as surveillance capitalism wants you to think there are only these two choices, nothing would stop kids (or anyone else, for that matter) from participating in society without a remotely-controlled tracking device packed with attention grabbers, but rather with a communication device that served its users
