BIRTH-RATE COLLAPSE 2035
Birth-rate collapse: the world stops replacing itself.
The birth-rate collapse is the biggest shift on this board and the one nobody votes on. 2 in 3 humans already live in a country that makes fewer babies than it needs. China: 7.9 million births in 2025, down 17% in 1 year, the fewest since Mao took power. South Korea: 0.72 children per woman in 2023, 0.80 after $210 billion. Italy: fewer births than in 1862.
Why? Not a mystery. Housing, childcare and education cost more than a second income covers. Women choose. The phone replaced the third child. Every rich country ends up here, and every poor country is on the same road: sub-Saharan Africa fell from 6.5 to 4.3 children since the 1950s.
The money hits in 3 waves. Pensions: fewer workers paying for more retirees, the pension math breaks. Labor: 85 million unfilled jobs by 2030. Growth: fewer minds, fewer ideas, slower economies.
Governments try 3 answers. Cash: South Korea spent $210 billion in 16 years for 0.08 of a child. Migration: the Gulf and America import workers, Europe argues. Machines: humanoids in the warehouses and the care homes, my $5 trillion call.
Then the outliers: Pavel Durov saying he has fathered more than 100 children by sperm donation, artificial-womb videos like EctoLife, a concept, not a clinic, Elon Musk warning that low birth rates end civilization.
My call: the world crosses below replacement by 2035. The UN says the late 2040s. The Lancet's IHME model says around 2030. I say 2035. Cash alone fails, migration decides who grows, and the robots raise the last generation.
