Neither does LLMs. Not without a monumental amount of human oversight and expertise.

Everyone not in a particular field asking LLM about said field is rolling bad dice.

I have published a LLM-assisted proof of a long-standing problem in convex geometry (70 years) while not being a specialist in convex geometry. I am a scientist and I have education and scientific experience in computer science and systems biology, but I was never a mathematician. So, well, you can definitely work across fields at least.
