Physical Cybernetics: Restoring Substrate, Homeostasis, and Continuous Dynamics 70 Years After the Dartmouth Divergence

Physical Cybernetics: Restoring Substrate, Homeostasis, and Continuous Dynamics 70 Years After the Dartmouth Divergence Special 70th Anniversary Commemorative Treatise (1956–2026)Series: QN-PC-2026-V1.0 | Completed: August 2026 | Published: September 2026 Abstract Background: In the summer of 1956, the Dartmouth Summer Research Project on Artificial Intelligence codified a foundational schism in the science of systems, consciously diverging from Norbert Wiener’s cybernetics to separate cognitive computation from physical thermodynamics. For seven decades, computing advanced under the Cartesian assumption that software logic is sovereign over an inert, passive hardware substrate. The Systemic Crisis: Exactly seventy years after this historical divergence, the digital abstraction has reached systemic exhaustion across the entire physical continuum. Inside silicon, memory-bandwidth bottlenecks leak periodic microarchitectural heartbeats (the 2.99 Hz Neural Pulse) vulnerable to unprivileged resonant preemption. At the electrical boundary, a six-order-of-magnitude temporal chasm (10 ms inference versus 25 ns physical switching) collapses Zero-Voltage Switching, dissipating over 4.2 MW of continuous waste heat per 100 MW datacenter. In macroscopic robotics, the tokenization of continuous torque and an 80 ms latency wall guarantee catastrophic out-of-distribution kinetic collisions, leaving disembodied foundation models unable to perceive their own battery voltage, motor thermals, or physical momentum. The Physical Cybernetics Framework: This treatise formalizes Physical Cybernetics, completing the seventy-year historical circle by reviving the embodied lineage of Norbert Wiener, W. Ross Ashby, and W. Grey Walter on modern silicon. By replacing discrete linguistic representations with 3D volumetric wave-relaxation continua (the Resonance Processing Unit), 25 ns sub-cycle FPGA determinism, thermodynamic noise harvesting, and native metabolic interoception (the Autonomic Basal Pacemaker), we demonstrate that genuine machine autonomy emerges not from scaling statistical parameters, but from continuous physical energy minimization and real-time homeostatic equilibrium. This establishes an authoritative, hardware-grounded paradigm for non-symbolic machine-to-machine communication, field-theoretic swarm governance, and sovereign physical intelligence. Key Architectural Pillars Pillar I: Substrate-Embedded Dynamics — Continuous electron wave-packet relaxation across 3D non-Euclidean Voronoi media (RPU) converging to ground-state equilibrium (Emin) at projected time-of-flight speeds. Pillar II: Sub-Cycle Determinism (τ ≤ 25 ns) — Single-clock hardwired FPGA arithmetic logic executing within active wide-bandgap carrier periods to arrest voltage sags and enforce continuous Zero-Voltage Switching. Pillar III: Thermodynamic Noise as Annealing Fuel — Spatial Stochastic Resonance harvesting ambient RF thermal fluctuations to drive barrier transitions and detect buried sub-threshold signals (SNR ≤ −18 dB). Pillar IV: Autonomic Interoception and Metabolic Homeostasis — The Basal Pacemaker coupling power-bus voltage, OS jitter, and structural somatic tremors to modulate the physical solver metronome (dtkernel). Pillar V: Non-Symbolic Field Extrusion & Swarm Consonance — Transmutation of perception directly into continuous scalar repulsion manifolds (−∇E), guiding physical inertia without discrete tokens or limit-cycle chattering.
