Yeah, the double standard... We are here on hacker news probably because our parents let us freely explore computers and the internet. "Screen time" wasn't even a concept. Most friends I talked to had really off-hands parents as well, parents were rarely involved or interested in what the kids were doing. Glad I didn't have overbearing parents who limited my technology use to the radio and LPs.
Well a lot of people, which must include many parents, cannot limit their screen time so is it any wonder they fixate on this with their kids?
