That's irrelevant. Cog-sci is largely folk psychology, and the problems in automating inference in AI demonstrate the model would eventually collapse. Question is how do we toss this model aside for an irreducible form of post-symbolic relationship between brains and machines?
I appreciate your gumption but I really think that you don't understand things as well as you think you do. Maybe read someone other than Paul Churchland.
Both Churchland's are out of date. Note the references above, this is a neurobiological, dynamic approach they're not party to. If you don't know what those are or optic flow, neural reuse are, then study them. Trad Neuroscience and cog-sci is no longer applicable.
