This article is not advocating AI driven development. It's arguing a human understanding the problem, and how best to solve it, is the most important work.

I’m not anti-spec. Far from it. I think rigorous, well-structured specs are about to be the single most important artifact in software. Read the book. Adopt the format. Use the tools. The mechanics matter and I’m not waving them away.

But the spec is a vessel. The recipe is not the cooking. If we pour mediocre understanding into a perfectly-formatted spec, we get perfectly-formatted slop, faster and at scale. The format is necessary. It is nowhere near sufficient.

The real work - the part no tool will do for you - is the human work of digging in. Of actually understanding the problem and the person you’re solving it for, deeply enough to have an opinion about what right feels like. Of capturing not just the requirements but the taste. The why. The elegance. The exact sweet spot of how it should work.
