I believe that the computational model of the mind is fatally flawed. Here are some reasons:
The most obvious reason is that all mental states have meaning — that is, they are intentional. Intentionality means that our thoughts are about something — there is always an object to which a thought points. I think about my vacation, or about politics or about my dog. But computation, understood as manipulation of symbols, is never intrinsically about anything. A computer matches a set of configurations of electrons to another set of configurations of electrons. What those configurations of electrons are about is not inherent to the computation — the meaning of this post as I type it is not inherently in the patterns of electrons on my screen but in the thoughts in my mind…Michael Egnor, “Why “the mind is just a computation” is a fatally flawed idea” at Mind Matters News
Summary: The mind is the opposite of computation. Mental states are always intentional and computation, by its nature, is never intentional.
