Has ChatGPT ingested all the latest medical and scientific literature and will it continue to do so as the literature is changed, amended or deleted? Does ChatGPT handle deletions in its machine learning? can it unlearn something or more specifically told something is no longer true? What medical boards are reviewing what data is ingested? Does ChatGPT know all possible drug combination interactions? Do people sign a disclaimer giving ChatGPT immunity from malpractice? Are doctors consulting with medical boards, ethics boards and lawyers before utilizing ChatGPT? Finally and most importantly, if ChatGPT were ever to be certified as a licensed medical doctor how could we prove it is following all the same rules and regulations doctors and medical groups are required to follow? How does one audit what advice this thing will give or has given?
