Repugnant Conclusion
Choose between 10 billion thriving lives and 100 trillion barely-worth-living ones.
Scenario
You must choose between two possible futures for humanity: World A: 10 billion people, all flourishing — high quality of life, strong relationships, meaningful work. World B: 100 trillion people, each with a life only barely worth living — just slightly above the threshold at which existence is preferable to non-existence. Total aggregate well-being is much higher in World B. Per-capita well-being is far higher in World A.
