Which AI? LLMs are coding facilitators and code producers.

A problem is solved when the solution is reliable. Non-deterministic Neural Networks are not reliable. In fact,

Sure, you can ask a brains-deficient operator to perform a huge task, but then you'll have to check the whole product, and that remains not cheap.
