A network under our feet
Beneath every forest floor is a network of fungal threads — mycelium — that connects trees, shares nutrients, and transmits chemical signals. A tree under attack by insects can warn its neighbors through this network. A seedling in shade can receive carbon from a sunlit tree nearby. The forest is not a collection of individual trees. It is a connected system.
What this teaches us about resilient systems
The mycelium network embodies three principles that apply directly to how we design technology systems:
- Redundancy — there is no single point of failure. If one path is broken, others exist. The network routes around damage.
- Resource sharing — surplus in one part of the system flows to where it is needed. The system optimizes for the whole, not the part.
- Distributed intelligence — there is no central controller. Decisions emerge from local interactions, and the system adapts without a brain.
What we can borrow
Our technology systems tend to be centralized, hierarchical, and fragile — designed for efficiency, not resilience. The mycelium model suggests a different approach: design for redundancy, share resources dynamically, and let intelligence emerge from connection rather than control.
The principle
Nature has been solving the problem of resilient networks for far longer than we have. The solutions it arrived at are not the ones we would have designed, which is exactly why they are worth studying.
Knowing better sometimes means looking at what has been working for a billion years.
