Imagine a world where hunger, that gnawing sensation we feel when our bodies demand sustenance, could be eliminated-not by more food, but by redesigning how our bodies experience hunger. Enter the thought experiment of the Cyberstomach , a theoretical construct to cure world hunger by externalizing the process that drives our need to eat.

Hunger is a system-a feedback loop in which the brain is "panged" by the body when it needs maintenance. If this need is unmet, suffering follows, leading to starvation, illness, and eventually death. But what if we could remove this pang? What if we could create a device-a cybernetic stomach-that doesn't send those painful signals to the brain, but instead moves the entire process outside the body?

At first glance, this seems like a futuristic solution to hunger. Yet, when we think about what hunger truly represents, we realize that the Cyberstomach doesn't solve hunger as we know it-it only relocates the problem.

The Thought Experiment

Let's define hunger in a more abstract way: as a signal, a message to the brain demanding maintenance for the body. In our natural biological systems, this signal comes from an internal organ, the stomach, which tells the brain, "Hey, I need energy!" The result is that familiar pang of hunger.

Now, imagine the Cyberstomach-a new internal organ, which is manufactured within a factory, that takes over this responsibility. With it, the internal signal of hunger is no longer felt by the organism. Instead, the body's need for energy is communicated externally to an institution: factories producing energy, schools educating people about food technology, and a vast network ensuring this external system works smoothly.

Here's the catch: just because we move hunger outside the body doesn't mean we've solved the core issue.

The system still needs to be maintained, and now that need is felt in a different way-through reliance on external infrastructure. The brain is still aware of this dependence; it's just shifted from the physical pang of hunger to the societal need for sustaining this external system.

Expressing the Cyberstomach Mathematically

To explore this externalization mathematically, we developed a framework for the cybernetic stomach, capturing the interplay between the body's internal maintenance needs and the external system's role in sustaining life.

In this system, we observe how hunger shifts between internal and external signals:

η

represents the efficiency with which this shift occurs. As hunger moves from internal to external, the body reduces its need while increasing the demand on the external system.

The final constraint ensures that the total maintenance requirement is met:

The Problem of Externalized Maintenance

This system suggests that the total hunger experienced by the organism doesn't disappear-it is merely redistributed between internal and external signals. The body still requires maintenance, and that responsibility is shared by the organism and the external Cyberstomach.

But as the Cyberstomach grows, it faces its own constraints. To model these, we turn to a unified fractal equation for the enclosure system -the larger system (factories, technology) tasked with sustaining life.

2. Unified Fractal Enclosure System (Final Corrected Form):

Formula not decoded

Where:

E s ( )

represents the enclosure size at a particular scale

s

, which could be the size of the organism's needs or the external system that replaces hunger.

H s ( )

, the growth term, scales logarithmically:

For systems below a critical size s max

, this term represents the growth of demand over time.

The terms in the equation represent a balance between growth and constraints. As the system grows, its energy needs increase, but so do its limitations (represented by the constraint term

C s ( )

.

The Problem of Maintenance

Now, what does this equation tell us about the problem of hunger? Essentially, it shows us that hunger isn't eliminated by creating the Cyberstomach-it's just shifted into another system. The biological hunger inside the body is replaced by a societal hunger: the need for maintenance now resides outside the organism, in the external systems that keep it alive.

Formula not decoded
As the system grows larger, both the need for energy (maintenance) and the constraints on supplying that energy increase. The equation highlights a fundamental tension in the Cyberstomach: while we may externalize the feeling of hunger, the need for maintenance-whether internal or external-remains an inescapable part of existence.

This function suggests that control decreases as complexity increases, but can be partially offset by the brain's adaptive capacity.

Complexity Evolution:

This differential equation expresses that the rate of increase in complexity is proportional to the lack of control.

This differential equation suggests that the brain's adaptive capacity increases in response to complexity but also decays over time.

What Does This Mean for Solving Hunger?

On the surface, the Cyberstomach presents a tantalizing solution to world hunger. It shifts the burden of maintenance from the body to external systems, which could potentially be optimized to produce abundant resources. But the equation above reminds us that this shift doesn't solve the problem entirely. The need for resources persists, and as external systems grow larger, they face their own constraints-energy, infrastructure, and societal maintenance costs.

In other words, hunger is not just a biological problem-it's a systemic one. As time goes on, the mind may become inexorably more involved with the maintainance problem than it was previously. We can move hunger outside the body, but the need for energy remains, and it simply transforms into the need to maintain the external systems that support life. Solving hunger, in this framework, is about finding ways to manage these external systems effectively-optimizing production, reducing constraints, and ensuring that the system remains sustainable.

Conclusion

The Cyberstomach thought experiment provides a new way of thinking about hunger. Rather than eliminating it entirely, we shift its location-from a biological process that pangs the brain to a societal process that maintains the organism from the outside. In doing so, we see that hunger is ultimately a problem of maintenance , whether it occurs inside or outside the body.

And through the lens of our mathematical model, we recognize that while shifting hunger externally might offer short-term relief, it introduces new challenges. As systems grow, they face increasing constraints and a growing need for energy-forcing us to confront the problem of hunger as part of the broader problem of sustaining life in a resource-constrained world.

Hunger, it seems, is not just a matter of feeding bodies but of maintaining the systems that make life possible. By integrating both the biological and mathematical perspectives, the essay creates a dialogue between abstract thought experiments and concrete mathematical reasoning-bridging the gap between philosophy and mathematics.
