Verification bandwidth as growth bottleneck

When AI makes execution abundant, the scarce human task becomes validation: auditing outcomes, certifying behavior, and underwriting responsibility. Economic gains from commoditized output will accrue to actors (people, firms, institutions) who control that verification capacity rather than to raw producers. — This reframes debates about AI impact from 'will jobs vanish?' to 'who controls verification and accountability?', with implications for regulation, credentialing, and market concentration.
