In this essay I sketch out a physical framework for the technosphere, Earth’s newest sphere. My goal is to articulate some of the implications of being human in the Anthropocene, given our inescapable role as parts of the technosphere. Its great and unknowable complexity can be skirted to some extent by focusing on limitations and imperatives incumbent on both human and technospheric behavior as imposed by physical necessity, i.e., by the requirements of organization and of physics.
Extending an observation by Stuart Kauffman about the biosphere, I note that there can be no Newton of the technosphere. There exists no fundamental “equation of motion” that, given sufficient information about initial conditions, can be used to foresee the technosphere’s trajectory through time. The reason is that, unlike in Newtonian physics, the space of possible states that the technosphere might come to occupy cannot be specified in advance. The behavior of the technosphere, except over short time scales (times less than the time required for major changes in its large subsystems), is unpredictable even statistically.
Although the technosphere lacks long term predictability, there is enough regularity in the world to have made possible our survival and the survival of other biological organisms, as well as the persistence of technological systems. Humans, as components of the technosphere, contemplating what tomorrow may have in store, feel their way ahead in short, uncertain (Bayesian) steps. Thus a reasonable starting point for investigating the human condition in the Anthropocene is to analyze the extant technosphere, i.e., to paint a picture of “technosphere now”, from which one hopes to gain some insight into “technosphere tomorrow”.
I thus proceed on the assumption that technospheric behavior will be sufficiently stable that it is meaningful to use a dynamical “snapshot” of “technosphere now” as a reference point for studying possible evolution pathways over timescales of interest to its human parts.
Certainly rapid shocks could occur that would upset this assumption, such as global nuclear war or impact by a large asteroid, but even much smaller changes in “technosphere now”, like an increasing rate of long-distance information transport, can be large enough to have significant effects on humans. Study of the dynamics of “technosphere now” can help develop our understanding of deviations from that standard for the same reason that the physiology of a healthy (homeostatic) human body provides a good reference point for studies of organismal pathologies. Several scenarios for modest temporal excursions from “technosphere now” will be examined in later chapters.
In order to move forward it is necessary to write down a suitable dynamics for the extant technosphere, that is, a set of rules that governs how the technosphere “works”. In the next few posts I will discuss general rules of system behavior applicable both to the technosphere and to its human and technological components.
