It makes sense. People said software engineers would be easy to replace with AI, because our work can be run on a computer and easily tested, but the disconnect is that the primary strength of LLMs is that they can draw on huge bodies of information, and that's not the primary skill programmers are paid for. It does help programmers when you're doing trivial CRUD work or writing boilerplate, but every programmer will eventually have to be able to actually truly reason about code, and LLMs fundamentally cannot do that (not even the "reasoning" models).

Medical diagnosis relies heavily on knowledge, pattern recognition, a bunch of heuristics, educated guesses, luck, etc. These are all things LLMs do very well. They don't need a high degree of accuracy, because humans are already doing this work with a pretty low degree of accuracy. They just have to be a little more accurate.
