The same productivity gain can conceal different human outcomes.
Two people may each double their output with AI. One may develop capability that transfers to later work. Another may lose performance when the tool, model, or accumulated relationship state disappears. A third may continue to perform well because valuable capability resides in a governed human–AI relationship.
Conventional output measures can record the gain without distinguishing these conditions. This proposal asks how economic measurement changes when the trajectory, agency, and resilience of the human participant are treated as part of the result.
