Scott Alexander argues that underpopulation concerns are overstated and likely irrelevant due to expected technological changes by 2100. Longer summary

Scott Alexander argues against worries about underpopulation, stating that while there may be some demographic shifts and challenges, they are not as dire as some claim. He presents data showing global population will continue to grow until 2100, and even countries with declining populations will still have substantial numbers. He discusses potential issues like age pyramid concerns and innovation slowdowns, but argues these are either manageable or likely to be overshadowed by technological changes. Scott concludes that long-term population projections are largely irrelevant due to the likelihood of transformative technological changes before 2100. Shorter summary
