The cost of local order

Life maintains its organization by drawing on energy gradients and exporting entropy. Intelligence can help it do this more effectively by compressing experience into useful models that guide action. What is preserved locally depends on processes that dissipate energy more broadly.

Start with energy gradients. Differences in temperature or chemical conditions provide opportunities to do work. One hypothesis places the origins of life around hydrothermal vents, where chemical gradients and mineral compartments could support early reactions. The precise origin remains unresolved, but the dependence persists: living systems draw on usable energy to sustain themselves.

An organism uses that energy to regulate its internal conditions, repair damage, and replace components. Resources enter; heat and waste leave. This exchange allows structures that would otherwise break down to persist. The organism produces entropy internally, but can export enough to keep its own entropy approximately steady while the combined entropy of organism and surroundings increases.

Inspired by Jürgen Schmidhuber’s Driven by Compression Progress, I see an important part of intelligence as progress in useful compression: discovering shared structure that lets a compact model explain more of our experience. These models connect understanding to survival. A model that helps an organism find food or avoid danger turns experience into actions that help sustain its physical organization.

Maintaining these models and acting on them both require energy. Intelligence can make an organism more effective at preserving itself, while the physical processes supporting that preservation continue to produce entropy. This connects the organization of information within a living system to the work of keeping that system alive.

As life proliferates, resources are needed to build and sustain more living systems. Intelligence can reinforce this process: better understanding helps us access and use resources, which can support further growth and learning. More capable models can expand what we can do with the energy and matter available to us.

Efficiency can lower the cost of individual activities, while growth can increase the total energy throughput and entropy production. Our capacity to thrive remains tied to this exchange. The same processes that allow life to preserve itself, develop greater understanding, and proliferate also contribute to increasing entropy in the larger system.
