Do you think being on Facebook, et al is a proper course in these subjects? How did you learn about them in the days before social media? The idea that corporate surveillance and conditioning is somehow required for growing up is silly and dangerous to the kids themselves.

Perhaps my argument is not clear enough, but it feels like we are not arguing the same point. I have no problem with technology, simply that kids should not be the product. There are plenty of higher-quality alternatives, just like there are alternatives to broadcast television and McDonalds.
