Fertility decline & demographic stagnation

Every developed country is below replacement. Under-counted by EA and e/acc. Civilizationally large.

Global fertility has fallen to ~2.3 and is projected to drop below 2.1 (replacement) within a decade. South Korea, Italy, Japan, and China are already at 0.7-1.3. Shrinking working-age populations break pension systems, slow innovation, and collapse housing markets. Causes: housing cost, childcare cost, cultural shift, biological fertility decline. Solutions span policy (childcare subsidies, YIMBY), technology (in-vitro gametogenesis, artificial wombs), and culture. Severely neglected in EA/e/acc canon.

The success vision · 30 years horizon

If we solve this, here is the world we get.

low

Before · today

TFR <2.1 in nearly every developed nation and approaching it in developing ones. Demographic collapse + dependency-ratio crisis baked in for the next 50+ years absent intervention.

After · 30 years

TFR above replacement in most willing societies. Family formation affordable, supported, and culturally celebrated. Demographic stability restored.

Population collapse due to low birth rates is a much bigger risk to civilization than global warming.

Population collapse from low birth rates is a larger civilizational risk than most mainstream X-risk. Has stated this repeatedly across years.

Demographic stagnation and complacency are under-discussed civilizational risks. Cultural risk aversion compounds into stagnation.
