I think intelligent and not-so intelligent folks have children. Though I do think the motivation has less to do with reflection than instinct or impulse. I've heard one theory that a desire to procreate stems from death-anxiety and a strong need to leave behind part of one's self. From an evolutionary point of view, that seems to make sense.

As for the dystopian ideas, I'll share some more thoughts when I'm not so tired.
