A shrinking global population could slow technological progress
Bubonic plague killed between one and two thirds of Europeans when it struck in the 14th century. Covid-19, mercifully, has exacted nothing like that toll. Its demographic impact, however, is likely to be significantly larger than the nearly 3m tragic deaths so far attributed to the coronavirus thanks to an associated, worldwide baby bust. Births fell by about 15% in China in 2020, for example, while America recorded a 15% drop in monthly births between February and November of last year. As a consequence, the pandemic may have brought forward the projected date of peak global population by as much as a decade—into the 2050s. A shrinking planetary population might seem like a wholly welcome thing given the world’s environmental challenges. But fewer people may also mean fewer new ideas, yielding a very different sort of future than optimists tend to imagine.
