In my experience, non-programmers lack not only the ability to translate concepts to code, but to formulate those concepts in the first place.

Ask someone who isn't a software engineer to guide you in developing a simple program. You do all the actual coding, they just tell you what they want to happen. You will find that most people are unable to describe even high-level actions in the form of a coherent, procedural sequence.

Even the best code-generating AI won't solve this problem, since it cannot generate useful code if the operator cannot articulate what they actually need.
