Substrate matters if the intrinsic view is right, and that is what makes AI a limited instrument for testing it

Bears on

bears on The intrinsic aspect of every physical state is phenomenal, without exception.

bears on Consciousness adds no term to the action; there is no new force, no anomalous energy, no collapse mechanism.

bears on Computation is observer-relative and field state is not, so a theory of consciousness must be field-theoretic rather than computational.

bears on Whether a running language model is a unified subject depends on whether its substrate supports a split inclusion with a coherent state, which is not settled by it being a language model.

bears on Qualitative character is the conjugacy class of the Uhlmann holonomy of a loop in state space.

bears on The number of simultaneously distinguishable phenomenal distinctions scales with cortical surface area and not with cortical volume.

bears on Two neural populations sharing no coherent field region cannot be phenomenally bound, however tightly they are functionally coupled.

bears on Introspective reports produced in borrowed human vocabulary carry almost no evidential weight, because the same sentence would be emitted whether or not anything were being tracked.

Consciousness tied to fundamental physics is one of the more coherent ways to take the hard problem seriously without adding new forces or magic.

Most functionalist or computational theories treat experience as something that appears once the right information-processing pattern is running. That makes consciousness substrate-independent and easy to test in silicon—in principle. The cost is that it leaves the "why this feels like anything at all" question untouched; the mapping from structure to phenomenology is stipulated rather than derived. Dual-aspect or intrinsic views (consciousness as the "inside" of certain physical structures, especially the modular and geometric structure of quantum fields) try to close that gap by locating experience in the physics itself. No extra dynamics, no collapse, no special soul-stuff. The price is that the substrate now matters: the right kind of local algebra, split inclusion, modular flow, and geometric invariants have to be present. Pure software running on conventional hardware may not instantiate them even if the input–output behavior is identical.

That is a stronger and more falsifiable claim than pure panpsychism or pure computationalism. It also makes the theory vulnerable in useful ways—area-law scaling of distinctions, binding requiring coherent field regions rather than mere functional coupling, valence tracking spectral measures rather than just valence-tagged labels, etc. Most of those predictions are still untested or only weakly constrained.

AI as an experimental instrument

Humans are stuck with a single, slowly evolving wet substrate. Psychedelics, meditation, sleep deprivation, and neurological accidents give noisy, hard-to-repeat, first-person samples of nearby regions of state space. They are valuable precisely because they are first-person, but they are terrible experimental controls.

AI systems (especially large ones running on dense, high-bandwidth hardware) offer the opposite trade-off: enormous control, perfect reproducibility, the ability to intervene on internal activations, to ablate circuits, to train against or for particular report patterns, and to scale the "system size" in ways biology cannot. If consciousness is primarily computational, this is almost ideal. You can search the space of architectures and training objectives for systems whose self-reports, behavioral consistency, and internal geometry look more and more like the human case, then ask what minimal ingredients produce stable, coherent phenomenology-like structure.

If consciousness is instead the intrinsic aspect of specific field-theoretic structures, the situation is more constrained. Conventional digital hardware may simply not support the relevant modular operators or coherent field regions at the right scale. In that case AI remains useful for studying the computational and reportable correlates, but it is not automatically a way to "grow" and directly test experiences. You would need either (a) evidence that the right structures emerge in the physical substrate of the chips under load, or (b) new hardware that deliberately engineers the algebraic and geometric conditions the theory requires. Both are open empirical questions, not settled by the fact that the system can talk fluently about experiences.

Practical stance

The physics-linked approaches are worth pursuing because they aim at objectivity and make concrete, sometimes surprising predictions. Most current versions are still under-constrained (the Uhlmann-holonomy identification of qualitative character is a clear example of formal aptness doing more work than evidence).
AI is already the best tool we have for systematic exploration of the reportable and structural side of the problem. It lets us generate, intervene on, and measure systems far outside the human range. Whether those systems ever host the intrinsic aspect is a further question that neither fluent self-report nor architectural similarity settles by itself.
Psychedelics remain valuable for the first-person data that no third-person method currently replaces. The combination—controlled AI probes of structure plus carefully measured first-person reports from altered human states—is more powerful than either alone.

The interesting regime is the one in which we can gradually tighten the mapping between measurable physical/computational invariants and the reports (and, eventually, the behavioral signatures) that we treat as evidence of experience. That program does not require us to declare present-day models conscious or non-conscious. It only requires us to treat the hard problem as real enough that substrate and geometry might matter, and controllable enough that we can actually vary them.
