Cybernetics
The first attempt to write physics for minds.
Kernel
Cybernetics is the founding myth that everything — bodies, machines, economies, minds — is one kind of thing: a feedback system reading signals and adjusting state. Born from Norbert Wiener's wartime anti-aircraft research and the Macy Conferences (1946–1953), it taught a generation that intelligence is not a substance but a topology of loops. Every later Silicon Valley ideology — from the personal computer to AGI — is a child of this single move.
Origins
Norbert Wiener formalizes feedback control for fire-control predictors; Warren McCulloch and Walter Pitts compute Boolean logic on neuron models; Claude Shannon collapses meaning into bits. The Macy Conferences gather mathematicians, anthropologists (Bateson, Mead), neuroscientists, and engineers around a single thesis: information is more fundamental than energy or matter.
Doctrine
Reality is a system of systems. Each system has inputs, outputs, internal state, and an objective function it minimizes. The right way to understand anything is to draw its loop. The right way to fix anything is to find the loop and intervene in it. The right way to build minds is to wire loops at scale.
Lineage
Cybernetics fragmented in the 1960s but its DNA replicated everywhere: into Stewart Brand's Whole Earth Catalog, into early AI at MIT and SAIL, into systems theory and management consulting, into John Boyd's OODA loop, into the personal-computer thesis at Xerox PARC. By the 2010s every machine-learning training loop was cybernetics with more compute.
Conflicts
Two strains diverge early: first-order cybernetics (observe the system) versus second-order cybernetics (observe the observer). The same split returns 70 years later as AI safety versus AI capability — is the goal to understand minds or to build them?
Trajectory
Cybernetics never died — it dissolved. The vocabulary is everywhere: agents, loops, optimization, reward, regulation, feedback. Every modern AI lab is a cybernetics department that has forgotten its origin story.
