Near as I can tell, folks have no idea (really) how bad it could be, since most of the really significant shifts have been in removing a lot of major problems. For example, eradicating Smallpox. Controlling Measles, Polio, Tetanus. Synthetic fertilizers eliminating famines in all but the most dysfunctional areas, etc. It used to be dying of disease or famine was a huge problem in much of the world. Now it is only in tiny, very broken areas, for relatively small portions of the population.
