My current one sure as hell is.
My previous one was, too.
The one I had as kid, well. He was old, stuck in old ways, but I still think he was decent at it.
But seeing the doctor is a bit more difficult these days, since the assistants are backstopping. They do some heavy lifting / screening.
I think an LLM could help with symptoms and then looking at the most probable cause, but either way I wouldn't take it too serious. And that is the general issue with ML: people take the output too serious, at face value. What matters is: what are the cited sources?
