The only other time in history with a significant population decline was the Black Plague. While the economic context was vastly different, its outcome offers a rough directional guide. The resulting labor shortage increased the value of skilled workers, broke the feudal system, and ultimately sparked the Renaissance.

Capitalism, socialism, and communism are all growth-based systems predicated on an expanding population to balance labor, capital, and demand. As the world enters demographic decline with shrinking working-age populations, the fundamental assumptions of these 500-year-old models collapse, requiring a complete reinvention of economic theory.
The difficulty in hiring young talent is not a temporary trend but a "new ice age." It is driven by a smaller Gen Z population compared to millennials. The problem will worsen: within a decade, more people over 65 will be leaving careers than 16-year-olds are starting them, creating a long-term demographic crisis for employers.
External shocks like wars or plagues don't destroy golden ages directly. The real danger is the subsequent societal shift from an open, exploratory "Athenian" outlook to a closed, protectionist "Spartan" one. This fear-based mentality stifles the innovation required for regeneration, leading to decline.
We have had housing technology for 10,000 years, yet have made it artificially scarce through regulation. This engineered scarcity prevents young people from starting families, directly causing the crash in birth rates that poses an existential threat to Western civilization.
As women gain more economic power and education, they often choose to have fewer or no children. This global trend is reversing previous fears of a 'population bomb,' creating a new challenge for nations struggling to maintain population growth and support an aging populace.
AI's arrival is serendipitous, providing the necessary productivity boost and labor substitution to counteract a future of economic shrinkage caused by declining global populations. Without AI, we'd be facing a crisis.
Marc Andreessen argues that AI isn't a job threat but a necessary solution. It arrives just as declining population growth and 50 years of slow technological progress in the physical economy would have otherwise led to economic stagnation and decline. AI and robotics are needed to fill the labor gap.
Current instability is not unique to one country but part of a global pattern. This mirrors historical "crisis centuries" (like the 17th) where civil wars, plagues, and economic turmoil occurred simultaneously across different civilizations, driven by similar underlying variables.
Many countries, including China, are facing a demographic crisis with falling birth rates and an aging population. This creates an economic imbalance with too few young workers to support the elderly. AI and robotics can fill this gap, effectively becoming the "young workforce" that sustains these economies.
Even if China could fully automate production to offset its shrinking workforce, its economic model would still collapse. AI and robots cannot replace the essential roles of human consumers, taxpayers, and parents, which are necessary for economic vitality, government revenue, and generational replacement.
