CONCEPT
The Criticality Stagnation Thesis
The proposition, derived from Per Bak's physics, that what appears as technological stagnation in the physical world is actually subcritical accumulation—slow steepening of the slope toward the critical angle—and that the AI transition marks not the end of progress but the system's arrival at criticality after decades of invisible grain-adding.
The criticality stagnation thesis bridges Per Bak's theory of
self-organized criticality and the stagnation thesis associated with thinkers who argue that fundamental progress in the developed world slowed around 1970. The thesis proposes that the apparent stagnation was not stagnation at all but subcritical accumulation: each programming language, abstraction layer, cloud service, and model architecture improvement was a grain on a sandpile of human technological capability, steepening the slope toward the critical angle without triggering a visible avalanche. The system
looked stable because perturbations were being absorbed locally—new tools adopted, new frameworks embraced, careers restructured without civilizational rupture. But each local accommodation was also a steepening. The slope approached criticality. And when the grains of December 2025 landed on the pile, the avalanche was not caused by those grains in any meaningful sense; it was caused by the global state of the pile. The disruption
