When the era of rationality finally dawned, it became clear to everyone that love doesn’t last. Furthermore, everyone agreed that humans spend too much of their youth immersed in and distracted by the misery of courtship and the agony of unfulfilled sexual attraction, and so much of their middle and old age in the sadness of waning attraction and regret. No one in the era of rationality was in favor of unavoidable human pain. So, when the entire human race decided that the complications caused by lust weren’t, in the end, worth it, they concluded that people would live much more calmly and pleasantly in a society where sexual competition was absent. It soon became clear that humans would be better off if everyone simply stopped reproducing.
