I hear what you're saying, and actually agree that - unfortunately - is the current state of LLMs today. But I think OP still has a point, and I'd argue as well that that is the aim of GAI, to be able to take a simple question, understand and produce the desired results.

As it stands, and as you mentioned, the current generation of LLMS seem a long way from there. Thus the need for prompt engineers. It'll be nice to see how long they take to crack this problem.
