But its trivial to fight against for the parents - just don't give them the damned phone/tablet/tv remote etc. Till teens there is little rational justification, and massive evidence against it.
But then real challenge starts - folks with microscopic attention spans themselves are supposed to actually spend hours with their kids on activities that hardly give any dopamine kicks. Kids are really just a brutally honest mirror image of the parents, and very few parents these days like that.
Had few colleagues recently visiting wedding in Singapore. The stuff they said about the city itself is pretty sad - no western parent they saw was actually raising their own kids, cheap (often abused) nannies from ie Philippines were in charge of that. They allow kids anything, no discipline, no boundaries because who wants to be fired if kids complain. And then when whole family minus mighty nanny goes to ie restaurant, they often saw a parent literally begging 7 year old to have 30 minutes for themselves ('I'll buy you any toy, any food, anything, just give us 30 mins please' kind of story). I wonder why they even bothered having kids these days if they couldn't care less about them afterwards, while giving it all to some empty corporate careers and partying.
Or those 'super parents' who travel with kids in the car a lot. Then you look inside and there are X tablets neatly arranged in the back. Our kids are used to stare outside instead or read books/magazines, important 'boredom management skills' that can't be taught otherwise.
