Rosa's paradigmatic small example is the Thermomix, a cooking device that tells the user exactly what to do at every step — what ingredients to add, when to stir, what temperature to set. The results are excellent. The meals are consistent. And the cook who uses it has stopped cooking. The cook has become, in Rosa's formulation, a program-executor — a person whose activity has been reduced from action (with attendant judgment, risk, responsiveness to circumstance) to compliance. The Thermomix is a small example of a pattern operating across every domain of algorithmic deployment: GPS displacing the driver's relationship with landscape, recommendation systems displacing the listener's encounter with music that challenges, coding assistants displacing the builder's encounter with the resistance of material.
The concept's force lies in the recognition that capability and agency can come apart. The person using the Thermomix is more capable — produces better meals more consistently — while being less agentive, less genuinely in relationship with the work, less exposed to the resistance of the material. The distinction matters because the capacities that make a human being more than a program-executor — moral judgment, aesthetic judgment, the judgment about what is worth doing — are cultivated precisely through the exercise of action in the Spielraum. When the Spielraum contracts, the capacities atrophy. Not because the person becomes lazy but because the conditions for their cultivation have been eliminated.
Rosa extends the analysis to AI with explicit directness. The coding assistant that implements the builder's intention without resistance reduces the Spielraum in which the builder encounters the material's resistance — the resistance that teaches, surprises, and transforms understanding. Each individual decision to use the tool is locally rational. The aggregate, across a career of such decisions, is the systematic contraction of the space in which the builder can exercise the judgment that distinguishes a senior engineer from a junior one. You On AI documents this tension in its chapters on ascending friction, arguing that the friction does not disappear but ascends to higher cognitive levels. Rosa's framework accepts the possibility but insists it is not automatic — the ascension requires institutional conditions that the market does not spontaneously provide.
The 2025 DIE ZEIT interview captured the stakes with Rosa's characteristic directness: have we all unlearned how to act? The answer, developed across Situation und Konstellation, is a clear yes — not because people have become lazy, but because the systems within which they operate have been designed to minimize the Spielraum in which genuine action is possible. The person has not changed. The structure of the situation has changed. And the structure now favors compliance over action, execution over judgment, echo over resonance.
The term draws on Rosa's sustained engagement with the German philosophical tradition of action theory (Hannah Arendt's distinction between work and action, Jürgen Habermas's communicative action) while extending the framework to the specific challenges posed by algorithmic systems. Rosa's 2025 articulation in Situation und Konstellation made Spielraum the central operational concept of his AI critique.
Action vs. compliance. Genuine action involves judgment, risk, and responsiveness to uncontrollable circumstance; compliance is execution of pre-determined instructions.
Spielraum is the interval. It is the space within which judgment must be exercised rather than delegated to the system.
Capability and agency differ. A person can be more capable (produces better outputs) while less agentive (exercises less genuine judgment).
Contraction is systemic. The market rewards smooth execution and penalizes the inefficiency of maintaining Spielraum, making individual preservation competitively costly.
The Thermomix principle. When a tool tells the user what to do at every step, the activity degrades from cooking to following — and the capacity that cooking developed atrophies.
