Re: the process of de-evolution has begun

The fact that we don't need to have tons of kids for survival is what marks the most recent evolutionary breakthrough.

Over the range of all possible future scenarios, # of kids has to be the most effective survival mechanism, by a long shot. The sheer weight of probability, and the initial exponential branching for the first few generations, would give one a massive advantage. In the gene propagation stakes, I think someone with a 90 IQ and 70 great grandkids is going crush someone with a 140 IQ and four great grandkids.
The only situation where this wouldn't be true is if society stratified into classes, and the lower classes got wiped out. But even there, sheer probably will propel some of those 70 grandkids and their kids into high IQ phenotypes, advantageous marriages, and attainment of upper class status.
