On Human Networks & Living Biosystems.

On Human Networks & Living Biosystems.

By Chris Arkenberg.

Increasingly, we live in a world defined by flat networks. Folks like Clay Shirky, Ben Hammersley, and others have observed in great detail how the design patterns of the internet are challenging and changing the landscape of human civilization. So many of our institutions have been built as hierarchical pyramids designed to exert the maximum degree of control over their domains. These top-down management structures have come to define business, government, the military, medicine, education, the family, and knowledge itself. Leaders rise to the top as centralized governors dictating down the chain how things should be, while workers march in step towards execution of their appointed tasks. Such structures were modeled after the clockworks & steam engines of classical mechanics, designed to be precise, rigid, and durable, capable of lasting hundreds of years. These structures informed the defining metaphors of our entire industrialized society.

Computer architecture recapitulated the mechanical metaphor by designating a central processor that assigned & managed tasks bussed out to sub-processors and specialized functional components. In this way the computer became more of a powerful extension of the industrial age rather than a stake in the ground of a new paradigm. While the mechanical metaphor gradually evolved into the computational metaphor which has defined the last two decades, it wasn’t until computers began to follow the model of telecom and began connecting with each other across flat networks that the seed of a biological metaphor began to take hold.

Nature, it seems, does not create very many rigid, top-down control systems. Those are too stiff and inflexible for the dynamics of life. Rather, nature evolves vast horizontal networks that assemble into specialized functions within their environment. For example, the messiest, most distributed organizational structure known - the human brain - does not have a top-tier manager or CPU. There is no executive function within the brain or its mind, though we typically like to think there is. Instead, the brain is a vast & mostly flat hierarchy that is bundled into loosely vertical functional bodies. These functional bodies are themselves existing across a mostly flat horizontal network of interactions. The thalamus receives all inputs and routes them up to higher cortical processing and lower hindbrain autonomic structures, into the amygdala for emotional content and across the hippocampus for memory, then down throughout the body. The processing chain is massively parallel, interconnected, and marked by complex feedback pathways. Mind arises off of these processes in a very ad hoc manner, always shifting, always flexible, and always derived from a mass summation across the network.

Mycelial networks offer another example. When we see mushrooms scattered across a forest floor we're not seeing individuals. Each mushroom growing from the soil is a fruiting body rising from the underground web-work of mycelia - the skeletal framework of the colony. Some mycelial colonies have been found to have areas extending over 2000 acres making them some of the largest superorganisms on the planet. The pattern suggests mushrooms as terminal nodes and mycelia as the network backbone.

In ecosystems, large predators constitute a form of top-down management but they themselves are part of the predator-prey relationship - a dynamic that must always seek relative equilibrium with the broader network in which it is embedded. Predators do not have a choice to over-consume prey or stockpile & re-sell it to others. Large ocean gyres also suggest a high degree of top-down control by seasonally establishing the engines of hemispheric weather. The North Pacific gyre becomes more active in the Winter of the northern hemisphere, driving the scale & frequency of storms hitting the pacific northwest of the United States. But the North Pacific gyre is an emergent structure that is itself built upon the properties of a nearly-infinite set of factors. It is not a regulatory structure or a governor by intent or design and there is no top-level group of components that determine its next move. It is a super-system derived from innumerable sub-systems.

Most importantly, all biological systems are guided not by top-down governors or control mechanisms but by feedback from the networks in which they are embedded. This is how nature regulates, preserves, and evolves itself towards greater adaptability. There is no fallible ruler driven to resource over-reach and myopic certainty. There is only the ongoing trial & error of embedded growth tempered by continuous communication between & within organisms.

As computers began to connect across the ARPANET, and with the dawning of the visual internet, the CPU evolved away from being specifically a central control system to become a node within a distributed network. This initial shift quickly challenged the established domains of publishing, content creation, intellectual property, and knowledge management while inviting the crowd into a shared virtual space of increasingly global identity & transaction. The advent of social networks established an organizational structure for connecting the human capital of virtuality, making it easier for like-minded people to connect & share & collaborate non-locally, subtly undermining the very notions of borders, statehood, family, and allegiance. Soon after, the mobile revolution has tipped everything on its side and bundled it into a portable device bringing instantaneous global communication & information access to most people on the planet.

The framework was laid for new forms of emergent, non-hierarchical, distributed collaboration & innovation, to both productive & destructive ends. Groups could now form and coordinate around affiliations, interest, and goals in ways that directly challenged the institutional structures monetizing our production & consumption and regulating our behaviors. It has become vastly easier for small organizations to take on multinational interests, whether in business & innovation or in power & politics. The conflicts we see across the world today are, in large part, a symptom of the younger generations leveraging flat network technologies to rise up against the older generations who long ago settled into their legacy hierarchical power structures. To paraphrase Ben Hammersley, the people who are running the world, who are entrusted with our future, are not able to understand the present. They lack the cognitive tools that are a basic part of the Generation C toolkit - the digital natives who grew up with a mobile in their hands and the internet at their fingertips, embedded in specialized networks that span borders and extend identity into the virtual.

The global disruptions that seem to characterize modernity constitute a civilizational correction driven by natural law. The DotCom bubble went through a correction, shedding excess value and pruning the garden of exuberant innovation to favor only the most fit. It was a good thing, if not painful. We witnessed the correction in the housing bubble and will likely see similar corrections in credit & commodities, as well as a painfully positive correction in energy, subsidized and under-valued for so long. The impacts of climate change are a correction imposed upon the legacy model of industrialization & growth by nature itself - the super-system in which all human endeavor is embedded and to which we are ultimately accountable.

The civilization correction is an emergent regulatory mechanism embedded within natural systems forcing our legacy human systems to progressively modify the unsustainable design patterns of our past. The mechanical metaphor & the computational metaphor are necessarily opening to include the biological metaphor. We can see this in every aspect of technology and it is equally emergent across human behavior & social systems. Nanosystems emulate biosystems. Computation & robotics are integrating with neurology & physiology. Individuals are finding agency & empowerment in leaderless multi-cellular collaborations. The built environment is becoming sensory-aware, communicating with itself through discrete feedback mechanisms. It can be argued that the emergence of the internet and of ubiquitous mobile communication & computation is an expression of our natural instincts to move into closer alignment with our environment; to follow the adaptive design patterns of nature in order to find a more sustainable & equitable posture for our species; a thermodynamic need to seek maximum efficiency in energy expenses. And to express a direct intervention programmed by nature itself to nudge the Anthropocene back towards equilibrium.

Such lofty ponderings aside, our world is undoubtedly approaching an inflection point. Everything appears to be upending and it’s all spread out in glorious detail for everyone to see. The feedback loop between humanity and it’s creations - the biological & cybernetic communication among individuals & groups & cultures & organisms & ecosystems - is tightening and getting more & more dense every day, feeding on itself and forcing exceptional degrees of novelty into becoming. It’s frightening & awesome and the Old Guard can barely see it happening right in front of their eyes. The shift may be apocalyptic, a sudden phase change, or an accelerated-but-managed transition... Probably it will be all of these things in differing degrees & locales. However it happens, the emerging paradigm is much more about networks, messaging, feedback, and biology rather than hierarchy, control, power, and mechanization. Nature is the super-system, the ultimate controller enforcing the laws of physics and prescribing the design templates for fitness & adaptation. If we are, as Kevin Kelley suggests, the sex organs of technology, then our technology is born from the natural imperatives coded deeply into our DNA.
