Today I allowed myself to think about things I don’t usually let myself think about, and I realized that I know how human beings are going to die out.
It’s essentially the opposite of ‘Survival of the Fittest’; the smartest, most capable people are going to clearly see how doomed the planet and life on it is becoming, and are going to choose not to bring babies into this. As they die without replacing themselves, the only humans that are actively reproducing will be those either too ignorant to objectively see how bad things are becoming, or too poor to prevent pregnancy. As this cycle inevitably repeats itself, only the least capable (or fittest) humans will be born and will reproduce. Until they are simply incapable of doing so in the wrecked world they’ve inherited.
