Anyone remember the BBC Micro?
There was a time when computers were something the kids were taught about, but the teaching seemed to shift away from computers to using standard office software. That's still useful, but even ten years ago school leavers were taking "computer driving licence" courses because the schools seemed to have failed them.
And today's parents are a part of that generation, which seems to have been sacrificed at the altar of Microsoft.
Frankly, while there's some weird stuff out there on the internet, and there are some nasty people, currently declaring that they are only arguing about ethics in game journalism, I also don't see any involvement of the internet in such dramatic and frightening cases as the child sex abuse in Rotherham.
My own feeling is that a lot of the scare stories, the political fantasies of predators on the internet, might be better dealt with as part of teaching sex and relationships. Things such as good passwords, and avoiding click-bait, are as significant as condoms. It's a different sort of relationship, but the internet is not different from Eastenders: people are telling the unusual and dramatic stories.
And we probably have our own myths.
