Cognitive Sedentarism

The book argues that the main risk of agentic AI is not that it executes tasks, but that humans stop exercising critical judgment over what they delegate. Drawing on the metaphor of chess and the story of Kasparov versus Deep Blue, it introduces the concept of "cognitive decoupling": the progressive loss of awareness of what the machine does on our behalf, with cumulative consequences for skills, creativity, and intellectual autonomy.

The work distinguishes three levels of delegation — cognitive offloading, outsourcing, and cognitive surrender — and proposes the concept of "System 3": an external artificial cognitive layer that is added to Kahneman's fast and slow thinking systems. It also analyzes four paradoxes of automation: AI slop, deskilling, automation complacency, and cognitive fatigue from intensive supervision.

The book closes with concrete governance proposals: designing environments that preserve human intervention, identifying what is non-delegable in each organization, and recognizing that productivity is a means to create value, not an end in itself. The central message is that the outcome depends not on individual willpower but on process design and governance.

1. Delegating execution is different from delegating judgment: cognitive sedentarism occurs when criteria and critical thinking are also handed over to the machine.
2. Individual efficiency does not equal systemic productivity: the mass adoption of AI does not automatically translate into organizational transformation.
3. Human supervision can degrade precisely because the machine is more accurate: automation complacency is a design risk, not an attitude problem.

What is cognitive sedentarism?

It is the deterioration of cognitive capacities through disuse: when we systematically delegate judgment to AI, reasoning, analytical, and creative skills atrophy from lack of exercise.

Which specific skills are at risk?

The book identifies critical reasoning, argumentative writing, tolerance for cognitive frustration, and the ability to sustain deep attention as particularly vulnerable. These are skills that develop and are maintained only through use: when AI systematically replaces them, they atrophy without the user even noticing.
