your doctor can have a bad day. and or be an asshole.

In 40 years, only one of my doctors had the decency to correct his mistake after I pointed it out.

He prescribed the wrong Antibiotics, which I only knew because I did something dumb and wondered if the prescribed antibiotics cover a specific strain, which they didn't, which I knew because I asked an LLM and then superficially double-checked via trustworthy official, government sources.

He then prescribed the correct antibiotics. In all other cases where I pointed out a mistake, back in the day researched without LLMs, doctors justified their logic, sometimes siding with a colleague or "the team" before evaluating the facts themselves, instead of having an independent opinion, which, AFAIK, especially in a field like medicine, is _absolutely_ imperative.
