That's like saying that a Google search beat real doctors, because the results surfaced a recent study they didn't hear about. That doesn't make Google better than doctors at diagnosing.
Yes, there are plenty of such cases but also many where Google gives correct answers and doctors are wrong unfortunately :/
It's very difficult to find a good doctor.
Many people are stuck and suffering without diagnosis because of real-life accessibility to good healthcare.
I'm talking about having practical access to a good, affordable, available AND knowledgeable doctor.
You get access to doctors which have time, and are near you, and in your budget, and they may not know your disease.
This is precisely where language models can help to sort and rank the information that is on the internet (if digested by a professional it's even better, but even raw, there is some value to it).
That's the reason why a doctor with Google is better than a doctor without Google. That doesn't mean that Google or ChatGPT without a doctor is a good idea.
