When Using AI Leads to "Brain Fry"

Three AI tools is where the productivity curve flattens. BCG's data shows intensive agent oversight produces a distinct cognitive fatigue, which runs directly counter to the "human in the loop" orthodoxy underlying most enterprise AI governance. The buried signal: autonomous agents requiring less oversight may produce better human outcomes than copilot patterns demanding constant attention, reframing the safety argument for more autonomous systems from ethical preference to operational necessity. If $1,000-plus of compute delivered monthly for $200 requires sustained human supervision to be trustworthy, the productivity math degrades faster than the pricing math improves. The causal language in a cross-sectional self-report survey deserves skepticism, and the prescription is indistinguishable from a BCG engagement scope, but the structural observation holds regardless of who funded it. Organizations deploying more AI tools without redesigning oversight models are accumulating cognitive debt, not compounding returns.
