The Modern Mind's Fatal Flaw: Broken Cultural Evolution

A recent essay argues that the modern mind has broken the Darwinian process of cultural evolution, threatening the long-term stability of civilization – and by extension, the investment landscape built on it. The thesis is simple: for most of history, hundreds of thousands of local peasant cultures competed in a slow-changing world, which kept cultural evolution healthy. Today, a global monoculture of wealth, peace, and rapid change has stalled that competition at the level of cultures. The result is falling fertility, decaying norms, and a shared value system that is losing its adaptive edge.

The essay identifies three possible fixes, each hard to achieve: let capitalism run everything, govern small groups with number-go-up tied to adaptation futures markets, or govern a large group with futures market estimates aimed at a civilization goal that conflicts with collapse – like having a million people live in space. None of these are easy, and all require a level of coordination that the current system lacks.

For investors, the argument carries weight. The essay points out that all structures – organisms, species, machines, minds, organizations – have historically rotted and decayed. The only consistent anti-decay force has been Darwinian evolution, where newer, less rotted versions replace older ones. Global governance, the essay warns, would likely suffer the same decay problem and might not even pursue the goals it was created for.

This is not a near-term market risk. But it is a structural one that could affect long-term asset allocation if the thesis gains traction. The essay's author, writing on AlphaScala, suggests that artificial minds and global governance would inherit the same fatal flaw unless we first fix the broken cultural evolution process.

The Cultural Evolution Mechanism

The essay traces the history of minds from DNA-based evolution through human culture to the modern mind. The key turning point: writing allowed shared world models to accumulate and be critically edited. Modern trade, travel, and talk accelerated innovation. But the very success of the modern world – wealth, peace, speed – appears to have broken the competition between cultures. Without that competition, status markers, norms, and shared values become less adaptive. Fertility drops, and civilization begins to decline.
