Book length development of my concept The Age of Malthusian Industrialism as a pretty bad future scenario that we should try to avoid:

In the decades and centuries to come, technological progress will slow to a crawl, as dysgenic reproduction patterns deplete the world’s remaining smart fractions (assuming that there are no abrupt discontinuities in humanity’s capacity for collective problem solving, such as genetic IQ augmentation or machine superintelligence). In the meantime, due to fertility preferences being heritable and ultra-competitive in a post-Malthusian world, populations will explode, as the world enters an epochal baby boom not long after 2100. This renewed demographic expansion will last until the world hits the carrying capacity of the late industrial economy, which will usher in the Age of Malthusian Industrialism.

Here is a list of “core articles” I have written on this to date:

• A Short History of the Third Millennium (2016)
• AoMI I: Where Do Babies Come from? (2019)
• AoMI II: Breeders’ Revenge (2019)
• AoMI III: The Geopolitics of the Age of Malthusian Industrialism (2019)
• AOMI IV: What Is the Maximum Population Earth Can Support? (2019)
