The LLM _HAS_ empowered the patient to act on his own health, which is undeniably a good thing.
Not sure about seeing the LLM as a companion.
Indeed the victory for the AI here is the ability to convince the author to take immediate action. The second win for the AI is the concise one liner the author tells the triage nurse so that her further diagnosis and treatment may proceed. A regular human being would be likely to start with a long form story of not feeling well for some time.
In this case, lab result analysis was entirely based around standard care protocols that LLM is really good at regurgitating back to you.
Yeah sure, anyone could probaly promt feed this into a homeopathy solution which would have killed the patient as per their own predisposed will. You could argue a standard programmatic diagnostic evaluation would be better but its not entirely clear wether human decision making improves based on webMD above an agitated Chatgpt urging you to seek professional help.
And now that I think about it more, no one except doctors and AI could reliably improve diagnosis based on a picture and lab results side by side. So if your healthcare system doesn't provide a response then chatgpt might actually be the closest neighbour in time of need.
