It seems closer to impossible than possible with the technology we have. Maybe something that isn't an LLM will come around that can do it, but even if that something else was capable of delivering perfect, ordered, maintainable, code without bugs and hallucinations it would have to be practically magical to understand completely what people mean when they talk about what they want because people are incapable of articulating what they want in a way that even other humans can understand.

For anything non-trivial, a technology capable of getting that information out of person without countless meetings would have managed to accomplish something far beyond what entire teams of humans are able to do today.

This is why if we haven't hit a plateau yet we very quickly will. All the good human generated slop has already been consumed and is being drowned out by vast amounts of the lossy, error filled, and highly concentrated slop AI produces from the human slop it was trained on.

Do you really think an LLM that spews out content based on statistical relationships is going to improve when it's been primarily trained on the slop of previous generations of LLMs? Hallucinations and errors will carry forward and spread like cancer. All the intelligence and creativity LLMs borrowed from human output will homogenize as the LLMs distill and then reiterate, effectively making bullet points out of bullet points, until their mimicry of intelligence becomes unintelligible.
