As long as LLMs need their users to "engineer" prompts for them to actually work well, clearly LLM-driven development is not exactly equivalent to back-and-forth conversation with a human programmer. In principle if what you say were true, software developers already wouldn't be needed anymore, because coding agents could talk to the customer directly and give rapid feedback to clear up even the smallest details. It should be uniformly better and cheaper than talking to a human developer, but that's not the world we currently live in. Currently we live in a world where LLMs that can disprove conjectures and find zero-days still need context engineering. We shouldn't anthropomorphise and assume that they will be exactly the same as us, they are undoubtedly useful but they need careful steering by specialists who understand how LLMs interpret prompts.
