My kids are significantly younger than that, but I've got to say I agree with the no-laptops-upstairs rule. Banning social media is too much, but I think monitoring what your kids are doing online is just a simple, sane precaution.
I've seen way too many kids lured off into predators' hands because their parents didn't know what they were up to. It doesn't take too many times of having to talk to a classroom full of kids about why their classmate was killed by a pedo freak to get to that point. I've had or been very near to that unpleasant experience three times, plus another time that the daughter of a close friend got lucky and was rescued before the perv she'd hopped a train to see was finished with her.
Needless to say when I see someone saying the world "isn't any scarier than when we were kids" it makes me either laugh or reach for a clue-by-four, depending on my mood.
