Chapter 1: The Intersection of Fungi and Technology

Recent research is opening exciting new possibilities in the realm of computing, particularly with the innovative use of mushrooms. As we embark on a transformative era, artificial intelligence (AI) is no longer a distant concept; it is now integral to our daily routines. From groundbreaking medical advancements to the promise of fusion energy, AI's influence is profound. Yet, its substantial energy consumption poses a significant challenge—training a single AI model can consume as much energy as 100 American households over a year, leading to a considerable carbon footprint. This stark reality raises concerns about how AI can align with our environmental goals.

Fortunately, a team of innovative researchers at the University of Bristol may have discovered a solution—mushrooms!

When I refer to mushrooms, I am speaking about fungi in general. The visible mushroom is merely the reproductive structure of a much larger organism known as mycelium. This mycelium forms a vast network of hair-like fibers that spread through their chosen environment. These networks not only connect with other fungi but also form symbiotic relationships with plants, allowing them to access vital nutrients.

Mycelium and plants engage in a mutually beneficial exchange: fungi break down complex soil compounds, releasing essential nutrients, while plants provide the fungi with high-energy sugars produced via photosynthesis. This interdependence creates a robust underground network, often referred to as the "Wood Wide Web," due to its resemblance to our digital internet.

Recent research indicates that this "Wood Wide Web" communicates not only through chemical signals but also via electrical impulses, akin to how transistors function in computer chips. This revelation opens the door to the possibility of creating fungi-based binary computers. Further studies suggest that these connections can mimic memristors, which are components that retain information about their previous state without requiring power.

While traditional memristors are difficult and expensive to fabricate, mycelium may offer a natural alternative. The synaptic connections in our brains operate similarly to memristors, enabling our minds to function efficiently with minimal energy. This suggests that mycelium could be harnessed to develop low-power neural networks, similar to those currently simulated by AI.

For context, a lab successfully built a computer using memristors that operated with only 1/800th of the energy used by conventional resistor-based systems. However, the challenges of scaling memristor technology limit its practical applications. In contrast, mushroom-based computing may provide a viable path forward.

The University of Bristol's Unconventional Computing Laboratory has been at the forefront of this research, demonstrating the feasibility of using mycelium as a component in computing. They have already showcased the ability to create simple logic circuits and binary code using mycelium connectors.

Professor Andrew Adamatzky, head of the lab, remarked, “At this stage, we are focused on feasibility studies. Our aim is to establish that computation is achievable with mycelium and to construct basic logical and electronic circuits.” Future advancements could lead to the development of more sophisticated mycelium-based computers.

Preliminary findings suggest that mushroom computing could significantly reduce power consumption compared to traditional methods while also being more resilient, as mycelium can self-repair unlike metal circuits. Although these fungal computers may operate more slowly than current technology, their speed remains adequate for certain applications that do not require immediate responses.

Professor Adamatzky is enthusiastic about the potential for mycelium in AI, stating, “Implementing neuromorphic circuits is a possibility... I envision creating a human brain using mushrooms.” His research indicates that this ambitious idea is within reach, potentially allowing for the development of powerful AI systems powered by fungi.

So, could this be the future of computing? Mushroom-based computers can replicate the functions of both resistors and memristors, facilitating the operation of advanced AI on minimal energy while still integrating with conventional computing processes. Additionally, they promise a significantly lower environmental impact compared to traditional chip manufacturing, which is often associated with destructive mining practices and high carbon emissions.

The main challenges ahead involve constructing intricate networks of mycelium and managing their slower processing speeds. However, advancements in genetic engineering could pave the way for overcoming these hurdles. Thus, while it may only represent a niche aspect of computing, the prospect of mushroom-based technology is incredibly exciting.
