Autocatalytic Sets
Collections of molecules (or technologies, or ideas) each of whose formation is catalyzed by other members—achieving collective self-sustenance that no individual element possesses.
An autocatalytic set is a network of elements in which each member's production is catalyzed by other members of the set, creating a closed loop of mutual enablement. Kauffman proposed autocatalytic sets as the origin of life: before DNA or self-replicating molecules, collections of simpler molecules catalyzed each other's formation, achieving collective self-sustenance. The mathematics demonstrate that in systems of sufficient diversity, with sufficient catalytic interactions, autocatalytic closure is not merely possible but expected—order for free operating at the chemical level. The concept extends beyond chemistry: W. Brian Arthur applied it to technological innovation (each technology enables technologies that enable it), and the AI moment exhibits autocatalytic dynamics where tools enable products that generate data that improves tools in self-reinforcing cycles.

The chicken-and-egg problem in biology's origin story is genuine: DNA stores information but cannot replicate without proteins; proteins perform catalysis but cannot be produced without DNA. Which came first? Kauffman's answer dissolves the paradox. Neither came first. What came first was a set
