Relational Friction
The specific kind of difficulty that is neither mechanical nor purely cognitive but interpersonal — the friction of sustained engagement with other practitioners through which vital engagement deposits its layers.
Relational friction is Nakamura's framework's most precise refinement of the debate about ascending friction. Neither Han's framework, which treats friction as a monolith, nor Segal's ascending-friction framework, which treats it as automatically relocating, fully captures what matters developmentally. The friction through which vital engagement is built is specifically interpersonal: the friction of working alongside others who hold different standards, who challenge assumptions, who force articulation and defense of choices. This friction operates across all levels of abstraction simultaneously and cannot be replaced by technical feedback, however accurate. Its preservation is the central structural challenge of sustaining vital engagement in AI-mediated work.

The junior engineer who refactors a module assigned by a senior colleague experiences friction at multiple levels. The work is mechanical. The module is tedious. But embedded in the mechanical work is the occasion for an interaction: the junior engineer does not understand a decision the earlier developer made. She asks. The senior colleague
