Controlled Friction as Engineering Practice
The deliberate introduction of friction-rich, AI-free work into an otherwise AI-augmented workflow — not as Luddite theater but as training, modeled on aviation's mandatory hand-flying hours, designed to maintain the diagnostic strata that daily automation erodes.
Controlled friction is this volume's name for the engineering practice of scheduling periodic 'bare metal' sessions during which developers work without AI assistance — writing code by hand, debugging by hand, deploying by hand — not as ideological protest but as skill maintenance. The practice is modeled on aviation's response to the same structural problem: autopilot erodes manual flying skills, the erosion is invisible until the automation fails, and the industry learned through accidents like Air France 447 that abstraction competence and underlying competence decay independently. The FAA mandates minimum hand-flying hours per recurrent training period as deliberate friction, introduced at some cost in apparent efficiency, as the specific institutional mechanism that keeps the pilot prepared for the moment the automation fails. Controlled friction extends this logic to software.
