From @ayjay on kids and social media:
My guess is that parents who continue to provide smartphones for their kids are, epistemically speaking, indistinguishable from those who declare that the 2020 Presidential election was stolen from Donald Trump. They cannot now back down; they have made themselves invincibly ignorant. Their sunk costs are just too great for them to consider evidence. They’ll keep doing what they’re doing, no matter the suffering their children undergo.
