I think there's a difference between questioning your doctor, and questioning advice given by almost every doctor. There are plenty of bad doctors out there, or maybe just doctors who are bad fits for their patients. They don't always listen or pay close attention to your history. And in spite of their education they don't always choose the correct diagnosis.

I also think there's an ever-increasing difference between AI health research and old-school WebMD research.
