I never believe in natural lang to tell computer to do things with an objective of getting certain result (been skeptical since pre-2011).

It wouldn't be used to fly plane without lots of physical buttons as a fallback.

Composing rigid instructions for computer is already hard, even with precise semantics defined. Even with static typed, dynamic typed, developers will try hard to get rid of a single bug.

AI will serve as a middleware with an objective of arbitrary result.
