CONCEPT
Phase Transition
The physicist's concept for discontinuous system reorganization — water to ice, coordination to judgment — that the Goldratt simulation uses to describe the AI moment's character.
Phase Transition is the term from physics describing a discontinuous reorganization of a system's behavior when a control parameter crosses a critical threshold. Water becomes ice at zero degrees Celsius; iron becomes magnetic below the Curie temperature; a gas becomes a plasma at sufficient energy. The change is not gradual. The system crosses a threshold and reorganizes. The new state has different properties, different behaviors, different constraints. The old rules do not apply — not because they were wrong but because the system they described no longer exists.

Goldratt, trained as a physicist, would have recognized the signature of phase transition in the AI moment immediately. When the coordination constraint shattered in December 2025, knowledge-work systems did not gradually improve. They reorganized. Projects that took quarters took days. Individuals accomplished what teams could not. Non-technical founders built technical products. The system did not get somewhat better at the old thing. It crossed a threshold and entered a new regime with different
