Mass society, for Arendt, is the sociological precondition for totalitarianism but also a structural condition in its own right. It describes a population that has lost the intermediate associations — guilds, civic organizations, local political bodies, robust family networks — through which individuals traditionally encountered public life. The result is a collection of atomized individuals who lack the relational scaffolding that would enable them to act together. Into this vacuum, mass movements and centralized administrative systems can expand with little resistance. The AI-augmented solo builder, working alone with powerful tools and connected to the world primarily through platforms she does not govern, recapitulates the structural position of mass-society man with disquieting precision.
Arendt's treatment of mass society drew on a European intellectual tradition — Tocqueville, Ortega y Gasset, Karl Jaspers — that had identified the hollowing of civil society as a distinctive modern pathology. Her contribution was to connect this hollowing to the specific possibility of totalitarianism and to the erosion of the public realm.
The framework's application to AI is structural. The technology enables capability at the individual level that once required collective organization, which sounds like liberation. But capability is not the same as power: the solo builder can produce what teams once produced, yet she remains dependent on infrastructure she does not govern, platforms whose terms she cannot negotiate, and markets whose logic she cannot influence. Her capability is vast; her political position is that of mass-society man.
The silent middle of the AI discourse is partly a symptom of this condition. Nuanced perspectives do not find public expression because the platforms that mediate public expression reward confident simplicity. The intermediate institutions that might have carried such perspectives — professional associations, trade guilds, local civic bodies — have been weakened for decades, and the AI transition has arrived in a civil-society landscape ill-equipped to process it collectively.
The Arendt simulation treats the reconstruction of mediating institutions as a priority response to the AI transition. Not because institutions can solve the technology but because they alone can carry the deliberation that responding well requires. Individuals cannot govern AI; they can only adapt to it. Institutions can govern AI, but only if they exist and have the capacity to act.
Arendt developed the concept in The Origins of Totalitarianism (1951), particularly Part III. It drew on her encounter with the European tradition of mass-society analysis and on her observation of how the Weimar Republic's collapse had been enabled by the atomization of its population.
Atomization, not togetherness. Mass society is a collection of individuals without the intermediate associations that enable collective action.
Precondition for totalitarianism. The mass-society condition creates a political vacuum into which totalitarian movements can expand.
Capability is not power. The AI-augmented solo builder has vast capability and minimal political agency.
Institutions required. The response to AI cannot be individual; it requires the reconstruction of institutions capable of collective deliberation.
