Having a doctor does not guarantee good judgement or good experience. But an LLM is guaranteed to have neither judgement nor experience.
Get a second opinion, or a third. Don’t get zero opinions.
And most of the time, you don’t need a 5% doctor, you need to find the one with the correct background of experience. Every misdiagnosis I’ve ever had was because I was at the wrong specialist. If you don’t think you’re getting the right care, sure, ask your LLM for alternatives. Then go speak to specialists in those fields.
