This is not true because experts in these domains don't make the same routine errors LLMs do. You may point to broad benchmarks to prove your point, but actual experts in the benchmarked fields can point to numerous examples of purportedly "expert" LLMs making things up in a way no expert would ever.

Expertise is supposed to mean something -- it's supposed to describe both a level of competency and trustworthiness. Until they can be trusted, calling LLMs experts in anything degrades the meaning of expertise.
