You assume that population will stabilize despite fertility falling univerasally all around the globe (with tiny but highly unpleasant exceptions). The economic issues are only projected to get worse. There are no known mechanisms for fertility to rebound. Yet you assume with certainty that the trend will reverse. Great to be you.

> You assume that population will stabilize Correct. This is seen in all manner of real world dynamic systems with constraint pressures. "Stabilize" in this context includes "bounces up and down between a few too many and a few too little". Now you're getting it. > There are no known mechanisms for fertility to rebound. Now you're being silly and all doom and gloom. > Yet you assume with certainty that the trend will reverse. Predict with high probability based on looking at lots of dynamic systems, yep. > Great to be you. This is hardly an esoteric or unusual viewpoint, perhaps you might look at cheering up and doing away with the OMG we have to breed w/out limit or die!! Seems a tad black or white for the much richer more complex world we live in.

  A lot of dynamic systems go off the rails and destruct, though. We haven't seen any population rebounds yet. Not even close.

      What if it's "dwindle" or "oscillate not far from zero" for humanity?
