The data gathering and entry can't be automated. It could be done manually, but at a very high cost (not a rounding error). Commercial insurers and Medicare certainly wouldn't be willing to pay. As a practical matter it's just not worth doing in the vast majority of cases.
Thanks again for explaining it so well. Usually me and you do not agree on healthcare issues, but this is one area where we seem to be on the same page.
As for diagnosing rare or very rare diseases, yes, it is possible, as you said. However, if you search for the rare disease I have in PUBMED, there are only 111 journal articles that have been written about it, and some are in foreign languages. The information on it is very sparse. I also doubt that it would be diagnosed by AI, as it effectively looks like "diabetes complications" (I have type 1 diabetes) and even though I had autonomic neuropathy at age 5, the onset of symptoms was very insidious.
