Positive Feedback Loops (Diamond)
The structural mechanism by which <em>initial advantages compound into insurmountable leads</em> — Diamond's central analytical device for explaining both civilizational divergence and the concentration dynamics of the AI transition.
Positive feedback loops are Diamond's core mechanism for explaining why apparently small initial differences between societies produce vast long-term divergences. In Guns, Germs, and Steel, he showed how early geographic advantages (access to domesticable plants and animals) produced agricultural surpluses, which supported larger populations, which generated more complex political organizations, which developed more sophisticated technologies, which conquered societies that lacked the cascading advantages. The mechanism is the same one Diamond recognized in AI development: early movers accumulate data, which improves models, which attracts users, which generates more data, which improves models further. The structural logic is identical across domains, and its distributional consequences — concentration rather than equalization — have the same mathematical inevitability.

The concept of positive feedback is cybernetic in origin but Diamond's application is specifically historical. In Guns, Germs, and Steel, the feedback loops operate across millennia: fertile crescent geography enables early agriculture, which produces sedentism, which produces demographic density, which produces disease exposure,
