Executive summary: This first part of a two-part review passionately argues that global depopulation poses a serious threat to human progress and well-being, emphasizing that more people mean more innovation, economic capacity, and moral value—while rebutting common concerns like climate change with the claim that technological solutions, not population decline, are what really matter.
Key points:
Depopulation is an underrecognized existential risk: The world has passed “peak baby” and is on track for a steep population decline, which could lead to a premature end to humanity’s story if current fertility trends continue.
Climate change won’t be solved by fewer people: Spears and Geruso argue that since we must decarbonize in the next few decades, depopulation occurring after 2080 is irrelevant or even harmful, as it reduces the capacity for innovation and infrastructure.
Innovation is driven by population size: The book highlights how more people lead to more ideas, technologies, and economic specialization—benefits that shrink in a depopulated world, even if no one is exceptionally talented.
People are not competitors for scarce resources—they are creators: The author pushes back on zero-sum thinking by emphasizing that having more people increases the chance that someone creates what you most value.
Ethically, more good lives are better: The post endorses the principle that a world with more happy, flourishing people is better than one with fewer, so long as those lives are worth living.
Debate should focus on externalities and intrinsic value—not coercion or racial anxieties: The author urges readers to steer clear of conflating concern about depopulation with reproductive authoritarianism or far-right ideology, emphasizing reproductive freedom and global well-being instead.
