There's an irony in worrying about youth data being taken by China while Elon Musk is accessing US Treasury data with a bunch of interns. Why should we trust Elon Musk any more than China?
Logan's Run is a good movie to cite. I remember being indoctrinated into "Don't trust anyone over 30". It wasn't just because the over 30 crowd didn't like Rock and Roll. They were sending our friends to Viet Nam. I guess I'm an old fart now but I'm from the generation that threw the bad guys out - if only for a while.
