He is repeating Thomas Malthus via a math lecture without saying point blank that some of us lesser peons haven't been deing on schedual because of the benifits of modern technology. We don't have world wars, epidemics or world famins anymore so we breed like bunnies. And the majority of us bunnies are not Phd material so we are just taking up space.
I hear this from Ivory Tower Liberals and the young idealists who carry their water every few years. You notice after identifying the problem he is neither volintering to commit suicide nor suggest a solution. Mostly the veild condensention towords how stupid most of us are.
Malthus also saw that societies through history had experienced at one time or another epidemics, famines, or wars: events that masked the fundamental problem of populations overstretching their resource limitations:
"The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race. The vices of mankind are active and able ministers of depopulation. They are the precursors in the great army of destruction, and often finish the dreadful work themselves. But should they fail in this war of extermination, sickly seasons, epidemics, pestilence, and plague advance in terrific array, and sweep off their thousands and tens of thousands. Should success be still incomplete, gigantic inevitable famine stalks in the rear, and with one mighty blow levels the population with the food of the world."
