My spouse is an hematologist+oncologist. She and all of her coworkers use ChatGPT. Before then, they look stuff up on UpToDate [ https://www.uptodate.com/login ] (they sometimes still do). I went to medical school for three years and quit because I couldn't stand the rote memorization part of the studies. Too many facts to remember IMO.

Even as an AI-neutral person, I'm very confident that AI/ML based computer systems, once trained specifically for medicine, will consistently do better than human doctors because believe it or not, there are a lot of human errors made in medicine field (doctors just don't admit that and we don't know) due to lack of time by doctors or incompetence or simply forgetting a fact or two that they should have checked when diagnosing or coming up with a treatment.
