I don't see how anything about what's presented here that refutes such claims. This mostly confirms that LLM based approaches need some serious baby-sitting from experts and those experts can derive some value from them but generally with non-trivial levels of effort and non-LLM supported thinking.

Yes, applied research has yielded the modern expert system, which is really useful to experts who know what they are doing.

It's not the "modern expert system", unless you're throwing away the existing definition of "expert system" entirely, and re-using the term-of-art to mean "system that has something to do with experts".
