Those symptoms could be caused by almost anything. In the end the author says they "likely have an autoimmune disorder". To be honest just from that list of symptoms, my first guess would be aging. I really don't buy that this person's AI tool did anything here. I think they probably got lucky even assuming the "autoimmune disorder" is the actual cause of these symptoms.

I get it that this sucks. But when you have a list of vague symptoms that aren't very serious, could be caused by anything, and your records show 30 visits to hospitals and specialists, and you start talking about experimental life extension treatments, the vast majority of doctors are going to write you off almost immediately as a hypochondriac.
It's the same in any profession. I worked at Geek Squad during college. Someone comes in 30 times because "my computers feels a little slow", we've ran every test we can think of, and nothing is wrong. In that case I'm going to place the blame on either user perception--this specific customer has unreasonable expectations about what is slow and fast. Or there's a minor non-serious issue with his computer that no one is likely to be able to diagnose without doing something seriously invasive that is likely to cause more harm than the issue.
