Yes, absolutely. But those people exist now, and you need to know how to deal with them because they're going to be a fact of your life going forward. The LLM's are going to tell you nonsense and pretend its the pure truth. The people you meet online are going to be mostly benign but interspersed with a few genuinely bad apples. You don't want all of that dumped on you at eighteen when you are apparently suddenly not a child any more.

I think it's much useful to teach kids early rather than late.
