What is disturbing about this is that the smartest men often don't reproduce. Isaac Newton, one of the smartest men ever, never married and never had children. Nicolaus Copernicus never married or had children. Adam Smith never married or had children.
Thomas Jefferson did, but only two of his children survived infancy. On the other hand, Erasmus Darwin had 14 children, and when his descendents intermarried with the Wedgwood family, they are still prominent even today. And I am not familiar with any of their descendents being politicians or murderers or thieves or anything bad.
I am reminded of the movie, Idiocracy.
I sometimes wonder what the world would be like if the smartest, most imaginative, most compassionate people had reproduced and populated the world. And the stupid and cruel had died out.
I'll say this: it would be a much better world.
