Never fear. In the developed economies child birth rate drops to one child per woman with greater educational opportunities and economic opportunities. For the most part you will will see this trend continue into the future. It's Africa and India that we have to worry about
It's very easy to be a futurist and a cornucopian. It's much harder justifying why we should have infinitely more mouths to take from that cornucopia.
And you know what? Each shipping container farm will have the yield of two freaking acres of conventional farmland. Once again, I fail to see how anyone can be a futurist and not a cornucopian.
I am also sad that Africa and India will leave Western civilization in the dust and go on to conquer the stars, but with a proper pro-humanity and pro-advancement mindset, we can join them.
They won't conquer the stars. The cold fact is that their societies are ticking time bombs, likely to suffer sweeping collapse and break-up within 50 years. If not that, then certainly a rising trend of authoritarianism to whip them into shape.
Democracy only works with smaller populations. This is something China understands and India will soon learn themselves.
With a youthful and growing populace, they are sure to take the lead. Civilizations that stop growing advancing die. Japan is a dying nation. Koreans will not exist in a few centuries if demographic trends continue. Germany, too, will either die or be remade by the vast influx of Arab immigrants.
Do we want to go this route?
