> Can't believe people are taking these highly dangerous drugs instead of mustering up a mass of eternal self-discipline they clearly already don't have and never will. Shame on them and the doctors!
That take does have some merit actually. The easier it is for people with low self-discipline to reproduce, the less self-disciplined future generations will be, and they might simply be unfit to handle future cataclysms.
Case in point: imagine teleporting to America in year 1000 and telling locals that they should go through a few plagues in order to build immunity. They'd call you crazy and then rip your heart out, and centuries later die from diseases brought by the Spanish.
