The turning point is not a single event but a period during which the speculative excess of the installation phase collides with the institutional deficit of the society, and the collision produces a crisis that opens a window for institutional reform. What gets built during that window determines the trajectory of the revolution for decades. The Victorian factory legislation, the New Deal, the post-war social compact — each was constructed during a turning point's window. The window opens because crisis concentrates political attention. It closes when the crisis passes, either because the institutional innovations have been built or because the political will dissipates. The historical record shows both progressive and regressive resolutions; the outcome is not determined by the pattern but by the choices made during the window.
The turning point's structural function is to mediate between installation and deployment. Installation's dominant logic is extraction — convert the gains of the new technology into returns for the parties that funded its development. Deployment's dominant logic is distribution — redirect the technology's benefits broadly through institutional mechanisms. The transition from one logic to the other does not happen automatically. It requires a crisis that reveals the insufficiency of the existing institutional arrangements, mobilizes constituencies for reform, and creates political conditions under which ambitious institutional innovation becomes possible.
Perez has argued that the current moment represents a turning point of unusual complexity — one where the incomplete deployment of the ICT revolution means the society is entering the AI reckoning with weaker institutional infrastructure than any previous turning point has required. The governance gap between technological capability and institutional response is wider than in any previous surge. The displacement is faster. The compression of obsolescence leaves less time for adaptation.
The turning point is also where the regulatory contest between installation-phase incumbents and reformers is fought. Incumbents use accumulated political influence to shape rules that protect their existing positions. Reformers demand institutional innovations that redistribute gains and support the displaced. The outcome determines the speed and completeness of the deployment phase. Where incumbents capture the regulatory process, deployment is delayed, gains remain concentrated, and the golden age is diminished or forestalled entirely.
For the AI revolution, the turning point's demands are specific: educational restructuring from training to development, labor market restructuring around judgment rather than execution, social insurance modernization for structural rather than cyclical displacement, and governance frameworks that enable democratic deliberation at the pace of the technology. The window is open. What gets built inside it is the only question that matters.
Perez identified the turning point as the pivotal concept of her framework because it is the moment when institutional agency matters most. The pattern she extracted from five revolutions showed that each turning point was won or lost by the quality of the political and institutional response during a brief window — and that the window closes whether or not the institutions are built.
Crisis opens the window. Political attention concentrates on institutional failure; reform becomes possible.
Contest between incumbents and reformers. Who captures the regulatory process determines the deployment phase's quality.
Not automatic. Progressive resolution requires political will; regressive resolution is the default if nothing is built.
Window closes. Political energy dissipates; the installation phase's distribution crystallizes into durable inequality.
AI's window may be narrower. The speed of the technology compresses the time available for institutional response.
The critique that Perez's framework risks becoming a secular theodicy — retroactively justifying every crash as necessary — applies with special force to the turning point concept. If the pattern is read as guarantee rather than possibility, it excuses inaction. The honest reading is that turning points can be lost as easily as won, and the historical record shows the 1930s and several other periods as failed or deeply delayed transitions.
