CONCEPT
Open System
Bertalanffy’s foundational distinction between closed systems that wind down to equilibrium and open systems that maintain themselves far from equilibrium through continuous exchange with their environment—the lens that dissolves the fiction of a deployed AI model as a finished, certifiable artifact.
An open system is Ludwig von Bertalanffy’s most productive concept, and the one that most directly challenges how we think about deployed AI. A closed system is governed by the second law in its simplest form: left alone, it runs down, entropy increases, disorder grows, and the system approaches equilibrium, which for a living thing means death. A living organism avoids this fate not by violating the law but by being a different kind of object with respect to it. “Every living organism,” Bertalanffy wrote, “is essentially an open system. It maintains itself in a continuous inflow and outflow, a building up and breaking down of components.” The organism holds itself in a steady state far from equilibrium through the sustained exchange of matter and energy with its environment; cut off the inflow and the organism slides toward the equilibrium it had been avoiding, which is death. The concept’s application to AI is structural rather than
