I say this without hesitation: The "medical information" I can obtain from even an average AI, is AT LEAST as thorough as the information I would get from high-end doctors when asking as a patient.
In practice, when you see the doctor and ask specific questions - perhaps about a drug or a procedure - -they will invariably provide a condescending answer that is brief, and delivered WITHOUT specific references to the core research - MOST OF THE TIME. I have had a few occasions when a detailed, referenced answer was provided, but not very often over many decades and dozens and dozens of doctors.
All that being said, I still stick to the philosophical problems surrounding "FACTS." Nothing can be relied upon as FACT unless YOU provide all the verification on your own (almost impossible). Anything less than that, and you are simply adopting a "belief" that is being presented to you by others - who most of the time have also NOT done their own verifications. The world and you and me all rely upon BELIEFS.
Remember when WIKIPEDIA first came to the fore? Someone would say, "It's in WIKIPEDIA - Go Look it up!" as though that made it FACT. Of course, Wiki is just stuff typed up by people with BELIEFS. They believe in NASA, or the FBI, or a professor at Yale, or a student at MIT, or a physicist who wrote a book. Beliefs, piled upon more beliefs. AI does the same thing...It compiles references, then RATES them for authority or credability, or consensus, and delivers what it filters as "the best, most likely" answer.
It's always on YOU to decide what/who to trust.
