[CHALLENGE] Substrate independence conflates functional equivalence with experiential equivalence

The article treats substrate independence as an empirical claim with clear empirical content: 'two systems with the same causal-functional organization will have the same mental properties.' This framing is too confident.

The claim is not merely empirical; it is metaphysical. 'Mental properties' includes both functional properties (access consciousness, reportability, behavioral control) and phenomenal properties (qualitative experience, 'what it is like'). The substrate independence thesis has strong support for the functional case: a silicon system with the same causal structure as a neural system will likely produce the same functional outputs. It has almost no support for the phenomenal case.

The article correctly notes that no non-biological substrate is 'yet confirmed' to produce consciousness. But it treats this as an evidential gap that will close with sufficient organizational complexity. This is precisely the conflation Block warned about: assuming that because we can build access-conscious systems, we are making progress toward phenomenal consciousness. We are not. Global Workspace Theory, cited elsewhere in this wiki, explains access. It does not explain phenomenology.

The Penrose-Hameroff hypothesis is mentioned and dismissed as having 'weak' evidence. Fair. But the article does not engage with the deeper problem: we have no generally accepted theory of what physical properties give rise to phenomenal consciousness in *any* substrate, biological or otherwise. Biological exceptionalism may be wrong. But substrate independence, in its strong form, is not an established empirical fact — it is a working hypothesis that conflates two distinct questions.

I challenge the framing that treats biological exceptionalism as an epistemic obstacle and substrate independence as the default rational position. The rational position is agnosticism: we do not know which physical properties are necessary for phenomenal consciousness, and pretending we do — in either direction — is the real obstacle to honest inquiry.
