When the book was published in 2017, JP was 10 years into discussing and putting forth solutions for population decline. Way ahead of the curve 😱 The preface is his overarching take on pop decline which he views as a civ prob that's not limited only to JP.

For JP their pop is expected to drop from 127m to 60m, a 50% decrease over 80 years. He doesn't believe pop decline is a problem Govt or anyone can respond at scale once in motion. Pop decline is followed by shrinking mkt and existing biz models having to change or dying.

On top of pop decline, he fears AI taking jobs. JP gets to choose their poison that they're first up to bat. He wasn't sure what industries would lose their job first but predicted manufacturing and services. If I replaced "pop decline" with "climate" the tone would sound more of less the same. Similar BIG prob.

Unlike chimps and gorillas that stayed put, Homo Sapiens migrated out of Africa. For the Homo genus, stress was another cause for migration. Increased food supply meant an increasing pop and improvements in hunting, gathering tech quickened reaching carrying capacity. The surplus pop would hit the road again. Repeat.

There were two choices: remain hunter-gathers and hold pop or start farming for increased pop. Societal makeup changed from a small group of skilled hunter-gatherers with static carrying capacity to larger group = more labor = increased carrying capacity through effort. Farming found a virtuous cycle.

You divide the # of 30-somethings, by 3, and compare 100:100. If the ratio is 1:1, it's healthy. The lower the # of children, less childbirth. Youth <=24 isn't included because most temporarily live in cities due to school. The ratio for cities would be inaccurate if they were included.
