How does the AI tell the difference between trustworthy YouTube postings, accidental misinformation, deliberate misinformation, plausible-sounding pseudoscience, satire, out-of-date information, and so on?

Some videos are a great source of information; many are the opposite. If AI can't tell the difference (and it can't) then it shouldn't be using them as sources or suggesting them for further study.
