Traces versus Specifications
A trace records a movement and carries the maker's biography; a specification exists all at once, computed from formula, made nowhere — the categorical difference AI introduces to creative production.
A line drawn by hand is a trace — it records movement, pressure, speed, hesitation, correction, confidence and uncertainty inscribed in its material character. Skilled observers read the hand-drawn line as a geologist reads strata: as a record of the forces that produced it. The line is not merely shape on surface but biography compressed into graphite and paper, the encounter between a particular hand and page at a particular moment. A machine-rendered line is a specification — it records no movement because no movement produced it. No pressure, speed, hesitation, biography. It is the result of computation, not the record of engagement. It has position but not history. This categorical difference illuminates what AI-generated artifacts lack: the temporal thickness, the weather-world situatedness, the traces that carry knowledge about the conditions of making.
