It is easy to overinterpret this based on the headline, the doctors were actually at a slight disadvantage. This isn't how they normally work, this is a little more like a med school pop quiz:

  An AI and a pair of human doctors were each given the same standard electronic health record to read – typically including vital sign data, demographic information and a few sentences from a nurse about why the patient was there. The AI identified the exact or very close diagnosis in 67% of cases, beating the human doctors, who were right only 50%-55% of the time.... The study only tested humans against AIs looking at patient data that can be communicated via text. The AI’s reading of signals, such as the patient’s level of distress and their visual appearance, were not tested. That means the AI was performing more like a clinician producing a second opinion based on paperwork.

"I don't know, let's run more tests" is also a very important ability of doctors that was apparently not tested here. In addition to all the normal methodological problems with overinterpreting results in AI/LLMs/ML/etc. Sadly I do think part of the problem here is cynical (even maniacal) careerist doctors who really shouldn't be working at hospitals. This means that even though I am generally quite anti-LLM, and really don't like the idea of patients interacting with them directly, I am a little optimistic about these being sanity/laziness checkers for health professionals.
