Here's a great example of how it handles uncommon medical questions.

Simple question, can trans women get endometriosis? This question is great for this because common sense will say, "no, of course not," and LLMs are nothing but distilled common sense. But common sense is often wrong. Common sense assumes far greater difference of the sexes tham actually exists. Here's what copilot has to say:

Copilot goes for the wisdom of the crowds, and the crowds fail. It even tries to respond thinking I'm talking about trans men rather than trans women.

And yet, here is a case report, clear as day, of a trans woman getting endometriosis.

And this phenomenon has also been observed in cis men undergoing estrogen therapy for prostate cancer.

I admit this isn't a common thing, as far as we know, among trans women. But the AI flat out says the possible is impossible.
