When reading articles like this, here's a quick check: Replace "YouTube" with "bookstores" and see if you're still outraged. Anyone can write a book, and the bar to getting a book published has absolutely nothing to do with the book's accuracy. If "Chariots Of The Gods?" can get published, you know publishers aren't doing sanity testing or any other kind of checks for the reliability of the content. And yet doctors buy books from bookstores, and use them to learn things. How do doctors know they're not getting nonsense? Because they know what real information looks like.

This is the biggest reason for teaching the basics of a broad variety of subjects: If you know what real information looks like, and how the real field basically fits together, you're less likely to be taken in by absolute nonsense. OTOH, if you get bad information to start, you're going to evaluate all subsequent information on that standard, and reject good information because it doesn't jibe with the bad stuff you've already internalized.
