The Chinese Room argument is silent on the question of the necessary and sufficient conditions for intelligence, thinking, and understanding. It’s an argument against philosophical functionalism in the theory of mind which states that it is sufficient to compare inputs and outputs of a system to infer intelligence.
The Chinese Room is also an argument that mere symbolic manipulation is insufficient to model a human mind.
As for the QM-equations, the many-body problem in QM is your enemy. You would need a computer far larger than the entire universe to simulate the quantum states of a single neuron, never mind a human brain.
Again. It's not an argument. It's a misleading intuition pump. Or a failure of philosophy to filter away bullshit, if you will.
Please, read again what I wrote.
Regarding "larger than Universe": "the argument" places no restrictions on runtime or space complexity of the algorithm. It's just another intuitive notion: syntactic processing is manageable by a single person, other kinds of processing aren't.
I'm sorry for the confrontational tone, but I really dismayed that this thing keeps floating and keeps being regarded as a foundational result.
