Minds have semantics. Minds necessarily have semantics.
Brains cause minds.
Any artifact that produced mental phenomena would have to duplicate the specific causal powers of brains, and it could not do this just by running a program. The way human brains actually produce mental phenomena cannot be solely by virtue of running a computer program. The Chinese room thought experiment. Imaginary souped up Chinese version of SAM implemented by Searle in the Chinese room. Necessarily Programming doesn't suffice for semantics.
