The 10x Mycelium Engineer
The 10x engineer is the supposed singular genius who works in isolation, guided only by intuition and raw talent, moving too fast and thinking too highly to be burdened by anything external. It mistakes ego for excellence and speed for strategy.
I like to think the 10x mycelium engineer is something of the opposite; a multi-disciplinary and multi-dimensional agent spanning collaboration between fungi and humans, taking their first principles from the mycelium itself. If we reframe around this idea, not an idol of exceptionalism but a model of distributed impact, a different kind of figure emerges. The 10x mycelium engineer cultivates signal and designs through dialogue with the fungus and with their team, sharing insight, surfacing opportunity and understanding. Their contributions multiply not because they move alone, but because they help everyone move more effectively. Not solely driven by ego and intuition, but managing a balanced interaction of experience, intuition, technical skill, and a dogged focus on the independent agency of the mycelium.
This article offers a distilled set of first principles that have emerged through years of designing with the whole body of mycelium as a dynamic and behavior-rich organism. These principles aren’t abstractions or high-level ideals. They’re working axioms: grounded in biology, shaped by experience, and refined through recursive collaboration. They reflect a way of engineering that acknowledges the fungus as an active participant in the design process whose physicality, memory, and temporality must be directly engaged. When you work with the whole mycelium you’re not just building materials, you’re shaping processes that think back, push forward, and grow with you.
First Principles
1. Respect Fungal Plasticity and Whole-Body Awareness
Filamentous fungi exhibit high phenotypic plasticity, enabling diverse physical expressions from the same organism, demanding respect for their dynamic, responsive nature. The fungus is a connected, historical, adaptive body, where local growth always reflects systemic influences over time. Its morphology is not just structure but a memory trace of environment, resources, and developmental history.

2. Design Through Dialogue, Not Control
Effective design emerges from iterative conversation with the fungus, not from control. Mycelium is not inert substrate but a responsive partner that senses, adapts, remembers, and makes trade-offs. Its decisions about durability or metabolic efficiency arise contextually, reflecting ecological signals, stress, and opportunity.

3. Form Is Memory, and Time Matters
Mycelial physicality is a historical record, each region of tissue reflecting past choices, environmental conditions, and developmental state. Growth unfolds on fungal time, a distinct temporality that requires patience and cadence; interventions and measurements must align with the organism’s own rhythms to reveal meaningful signal.

4. Growth Metrics Are Independent and Tunable
Specific growth rate and growth velocity are fundamental, independent, and tunable dimensions of fungal development. Decoupling biomass accumulation from spatial expansion opens broader design space, allowing structure and reach to be engineered separately.

5. Structural Investment Reflects Ecological Context
Thallic reinforcement is not a fixed trait but an ecological and contextual decision. Mycelium invests in durability in response to scarcity, threat, or opportunity, shaping toughness as an emergent outcome of its environmental context.

6. Complexity Is Signal, Not Noise
Fungal responses are inherently high-dimensional, where complexity itself carries meaning. Embracing and utilizing this richness through featurization, dimensionality reduction, and predictive modeling reveals coherent trajectories, while direct observation (as a counterweight to abstraction) and quantitative tools transform raw data into actionable design insight, keeping ego in check by grounding assumptions in biological reality.

7. Scaling and Experimentation Are Recursive Learning Systems
Scale is not a ladder but a dialogue across bench, pilot, production, and digital formats. Additionally, fungi are not chemical reactors, so experimental design must account for noise, allocation, and time. To address these biological realities adaptive learning prioritizes experiments that maximize information over effort, while system-specific platforms and direct observation ground assumptions. Together, these recursive exchanges reveal scale-dependent behavior and accelerate convergence on meaningful outcomes.

8. Design Is Behavioral Guidance Through Context
Mycofabrication is a dialogue where form emerges from context, not imposition. Environmental, spatial, and temporal conditions act as proposals that guide physical reinforcement and memory. Parameters such as nutrients, substrate firmness, and spatial distribution function as levers shaping fungal architecture and behavior.

9. Relational Design Manages Risk
Durability, strength, and adaptability emerge from distributed relationships within the network. Whole-body design is essential, as global architecture determines function. Anticipating cascading trade-offs between speed, morphology, and resilience requires treating fungal architecture as a system of relationships rather than isolated traits, where multiple solutions may exist but not all serve the same purpose. Recognizing this allows for maximizing possible solution spaces and minimizes pre-empted failure.

10. Engineering Requires Relationship Building
Effective mycelium engineering grows from long-term familiarity with fungal strains. Strains exhibit recognizable personalities, and working with them as individuals deepens collaborative design, building insight that only emerges through sustained relationships.

Full Framework: Expanded Principles
For those who want the full articulation, the longer version below organizes each principle in more depth.
Mycological Learning
Respect for Physical Plasticity: Filamentous fungi exhibit high phenotypic plasticity. This enables diverse material expressions from the same organism but requires respect for their dynamic, responsive nature.
Whole-Body Awareness: The fungus is a connected, historical, adaptive body. Local growth reflects systemic influences over time.
Dialogue with the Fungus: Effective design emerges from iterative conversation, not control. Fungi sense, adapt, remember, and make trade-offs.
Form Reflects Experience: Morphology is a memory trace of environment, resources, and developmental history.
Growth Rate vs. Growth Velocity: These are independent and tunable. Decoupling biomass accumulation from expansion opens broader design space.
Distributed Memory & Decision-Making: Growth patterns emerge from spatially and temporally distributed signals rather than a central controller.
Temporality: Fungi operate on distinct timescales. Patience and cadence attuned to fungal time are essential.
Structural Reinforcement as Investment: Durability is an ecological decision, not a fixed trait. Mycelium invests in toughness in response to threat, scarcity, or opportunity.
Relationship Building: Long-term familiarity with individual strains deepens collaborative design; strains have recognizable personalities.
Experimental Learning
Biological Realism: Fungal systems don’t behave like deterministic chemical reactors. Experiments must reflect biological realities of growth, allocation, time, and noise.
High-Dimensional Awareness: Fungal responses are complex. Use featurization, dimensionality reduction, and uncertainty quantification to explore response spaces meaningfully.
Poly-Directional Scaling: Scale is not a ladder but a learning system. Up, down, lateral, and digital scaling in dialogue reveal emergent, scale-dependent behaviors.
Adaptive Learning: Prioritize informative experiments over sheer quantity. Target high-uncertainty or high-value regions to maximize learning per effort.
Complexity as Signal: Embrace multidimensional responses; use statistical and machine learning to translate them into coherent trajectories.
Direct Observation: When in doubt, look at the hyphae. Indirect proxies risk being misled by fungal plasticity.
Quantitative Modeling: Observations gain leverage when coupled with predictive modeling that tunes network complexity to outcomes.
System-Specific Platforms: Design experimental systems tailored to the feature or question at hand; simpler when possible, bespoke when necessary.
Temporal Alignment: Measurements and interventions must match fungal response cadence.
Design Learning
System - Organism Reciprocity: System design must adapt to the fungus, and the fungus adapts to the system.
Specifying the Specification: Design begins with understanding which features matter, at what fidelity, and for what purpose.
Fractal Translation: Practices should translate across scales and functions, but without assuming uniform behavior.
Durability as an Emergent Property: Material toughness arises from fungal architectural decisions, not strain identity alone.
Designing with Behavior: Material form reflects foraging, reinforcement, and memory. Design means guiding behaviors, not imposing form.
Context over Control: Mycofabrication is a dialogue; environment, space, and timing are proposals that elicit fungal response.
Parameters as Levers: Nutrient ratios, substrate firmness, and incubation conditions all steer fungal architecture.
Whole-Body Design: Durability and function arise from total network architecture; design must consider global structure.
Mycelium as Historical Record: Tissue reflects past choices; design should shape that record intentionally.
Ecological Responsiveness: Success depends on ecological context; inoculum geometry, substrate, timing, and competition.
Temporal Rhythm: Design must align with fungal temporality.
Relational Risk Management: Anticipating cascading trade-offs (speed, strength, morphology, adaptation) requires treating fungal architecture as distributed relationships.
Final Thought
Whether distilled or expanded, the value of these principles lies in their practice, turning lessons from fungal growth into habits of engineering and collaboration. Learning from fungi means building not only resilient materials, but resilient patterns of thought and partnership. That, more than speed or ego, defines the 10x mycelium engineer.
