The progressive decay of the capacity for sustained, unaided concentration that occurs when practitioners rely continuously on AI assistance — incremental, imperceptible, and grounded in the neuroscience of synaptic pruning.
Depth atrophy names the progressive decay of the capacity for sustained, unaided concentration that occurs when knowledge workers rely continuously on AI assistance. The phenomenon is grounded in the neuroplasticity research that has established the brain's capacity to rewire itself in response to the demands placed upon it — the principle that cognitive circuits strengthen through deliberate exercise and atrophy through disuse. The AI-augmented workflow exercises the circuits that support evaluation, prompting, and selection. It does not exercise the circuits that support sustained engagement with a single hard problem over extended periods without external assistance. The circuits that are not exercised undergo synaptic pruning — losing the connections that supported the unused capacity. The atrophy is incremental, imperceptible, and cumulative.

The neuroscience foundation is Donald Hebb's 1949 principle that neurons that fire together wire together, extended by decades of subsequent research into activity-dependent plasticity. The cognitive implication is that capacity is maintained through use — the skill that
