The Thermomix Example

In the AI Story

Rosa introduced the example in a 2023 Philosophie Magazin interview and expanded it across Situation und Konstellation (2025). The force of the example lies in its ordinariness. The Thermomix is not an exotic AI system; it is a kitchen appliance. And yet the structural transformation it produces in the activity of cooking is the same transformation that algorithmic systems produce across every domain in which they are deployed. The cook who follows the Thermomix's instructions produces good food. But the relationship with the food, the material, the act of cooking itself has been fundamentally altered. The cook no longer needs to judge when the onions are ready, no longer needs to taste and adjust, no longer needs to develop the tacit knowledge that distinguishes a skilled cook from a beginner. The device does all of that. The cook complies.

The example's analytical reach extends far beyond cooking. Rosa uses it as a template for understanding the GPS navigation system (which eliminates the driver's relationship with landscape), the recommendation algorithm (which eliminates the listener's encounter with music that does not fit established preference), and the AI coding assistant (which eliminates the builder's encounter with the resistance of the material). In each case, the activity becomes smoother, faster, more efficient. In each case, the Spielraum — the space for judgment, the interval in which genuine action can occur — contracts. The cook follows instructions. The driver follows the route. The listener follows the algorithm. The builder follows the output. The world is more available. The world is more controllable. The world is more mute.

What makes the Thermomix example rhetorically powerful is its refusal to stage the problem as exotic or dystopian. The device is not malevolent. It does not surveille. It does not manipulate. It simply tells the user, with excellent reliability, exactly what to do. And in doing so, it eliminates the conditions under which cooking could be a site of resonance — the encounter with material that resists, with technique that must be adjusted, with the particular history that this ingredient in this kitchen at this moment brings to the act of preparation. The Thermomix produces excellent meals and destroys cooking as a resonant practice. Both claims are true simultaneously. The framework's power is the recognition that the first claim does not redeem the second.

The extension to AI coding assistants makes the stakes explicit. When a builder describes an intention to Claude Code and receives a working implementation, the builder has produced an artifact. The builder may not have experienced any encounter with the resistance of the material, any moment of genuine judgment, any instance of the kind of friction that would have developed the geological understanding of a system. The output is present. The developmental experience that would have accompanied its production in a non-AI-augmented workflow is absent. Over a career of such interactions, the builder can produce a great deal and cultivate very little. The Thermomix cook at scale.

Origin

Rosa introduced the Thermomix example in a 2023 interview with Philosophie Magazin and extended it across his 2025 Situation und Konstellation. The example functions as both a rhetorical device (accessible, ordinary, not dependent on exotic technology) and an analytical template (a small case that illuminates the structural logic of algorithmic systems across every domain).

Key Ideas

Action becomes compliance. The cook who follows the Thermomix's instructions has stopped cooking and started executing a program.

Excellence and impoverishment coexist. The meals are better than the pre-device cook's output; the cook is less developed than the pre-device cook.

The template generalizes. GPS eliminates the driver's landscape relationship; recommendation systems eliminate the listener's challenging encounter; AI coding assistants eliminate the builder's material resistance.

No malice is required. The Thermomix is not manipulative; it simply optimizes the activity, and the optimization eliminates the conditions under which the activity could be resonant.

The stake is capacity, not capability. The Thermomix user becomes more capable (produces better outputs) while becoming less capable of the judgment that the activity previously required.

Debates & Critiques

The example has attracted criticism for being too schematic — some critics, including Luciano Floridi, argue that the real choice is rarely between full compliance and full action, but between different distributions of judgment across human and machine. Rosa's response is that the framework is not meant to condemn any specific distribution but to make visible the systematic tendency of algorithmic deployment to shift the distribution toward compliance, and that the shift is driven by market pressure rather than by thoughtful design. A related debate asks whether the loss of tacit cooking knowledge is genuinely a loss; some economists argue that if the Thermomix produces good meals reliably, the lost capacity is not missed. Rosa's response is that the missed capacity is not recognizable to those who never developed it, which is precisely the structural problem — the loss is invisible to its victims.
