Can Mushrooms Be Used as Living Computers?

Bottom line: Mushrooms may be used as biological computing mediums that mimic simple logic gates, but they are not capable of performing complex computations or functioning as traditional computers.

In 2010, a scientist named Andrew Adamatzky published a paper titled “Mycelium as a Computing Medium: A New Paradigm in Biological Computing.” The paper described how a common button mushroom, Agaricus bisporus, could be used to perform basic computational tasks. It wasn’t the first time people had imagined fungi doing math, but it was the first time someone had tried to make it happen.

Adamatzky and his team found that the mycelium — the root-like network of the fungus — could generate electrical activity that resembled logic gates. These are the building blocks of digital computation. By arranging the mycelium in specific configurations, they created simple circuits that could perform tasks like AND, OR, and NOT operations. It was a breakthrough, but one that people often misunderstood.

The key point is that these fungi weren’t computing in the way we think of computers. They were responding to electrical stimuli in a way that mimicked digital logic. It was more like a biological analog circuit than a true computer. The results were intriguing, but the systems were rudimentary and required constant external input. They couldn’t store data, run software, or even process information the way modern computers do.

The idea that mushrooms can be used as living computers in the same way that silicon chips power our phones and laptops is a common misconception. The mycelium-based circuits Adamatzky created were far from practical applications. They were more like a biological version of a simple logic gate — a fascinating but limited tool. The research is more about exploring the potential of biological materials for computation than creating a viable alternative to silicon.

To understand how mushrooms might be used in computing, we need to look at their unique biology. Mycelium is a vast network of hyphae — thread-like structures that can span several meters. These hyphae can conduct electricity, a property that has been studied for decades. In the 1950s, scientists discovered that certain fungi could generate electrical signals, and more recently, researchers have found that these signals can be manipulated to create patterns that resemble digital logic.

Adamatzky’s work built on this by showing that mycelium could be used as a medium for electrical signals, much like a circuit board. By applying a voltage to the mycelium, he could create patterns of electrical activity that mimicked the behavior of logic gates. The challenge was that these signals were not stable and required constant input. They were more like a biological version of a simple switch than a full-fledged computer.

Despite the limitations, the field of biological computing is growing. Researchers are exploring how to use fungi, bacteria, and even plant cells to create new kinds of computing systems. The goal is not to replace silicon but to expand the boundaries of what computing can be. For example, some scientists are looking into using fungi to create biocomputers that can process information in parallel, much like the human brain.

One of the most promising applications is in the field of bio-sensing. Fungi can detect changes in their environment, such as temperature, humidity, and even chemical signals. By integrating these sensing capabilities with computing, researchers hope to create systems that can respond to environmental changes in real time.

The challenge lies in making them stable, scalable, and efficient. While the idea of using mushrooms as living computers is still far from reality, the research is opening up new possibilities for how we think about computation.

Despite the progress, there are still many unanswered questions in the field of biological computing. For example, how can we make these fungal circuits more stable and efficient? Can we create more complex systems that can perform multiple tasks simultaneously? And what are the long-term implications of using biological materials for computing?

Another major challenge is the scalability of these systems. While small-scale experiments have shown promise, creating a full-fledged biological computer that can process complex information remains a significant hurdle. Additionally, there are ethical and ecological concerns about using living organisms for computing, particularly in terms of sustainability and environmental impact.
