Totally agree, it can be a bit of an echo chamber. I had an infection post-dental-work. Bing Chat insisted I had swollen lymph nodes from a cold that would resolve on their own, then decided I had a salivary gland infection. After a follow-up with a real-world ENT, it was (probably accurately) diagnosed as a soft-tissue infection that had completely resolved on two rounds of antibiotics. The AI never raised that possibility, whereas the ENT and dentist examined me and reached that conclusion immediately.

I do think AI is great for discussing some health things (like "how should I interpret this report or test result?"), but it's too echo chamber-y and suggestion-prone for accurate diagnosis right now.

Ya I wouldn't trust it for diagnosis at this point. But it can help you get pointed in the right direction so human, tests, and the scientific process can try to figure out the rest.

Doctors struggle with diagnosis as well. I have stories and I bet everyone has stories about being passed from doctor to doctor to doctor, and none of them talk to each other or work holistically.
