The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.

Many cognitive psychologists see the brain as a computer. But every single brain is absolutely individual, both in its development and in the way it encounters the world.

Most theoretical work since the proposals of Hebb (1949) and Hayek (1952) has relied upon particular forms of dependent synaptic rules in which either pre- or postsynaptic change is contingent upon closely occurring events in both neurons taking part in the synapse.

Hebb place the Law of Effect at the synaptic level by proposing a correlation model of synaptic modification similar to that of Hayek (1952). This work was seminal in providing a basis for many subsequent theoretical studies . .

Evolution works by selection, not by instruction. There is no final cause, no teleology, no purpose guiding the overall process

Your brain develops depending on your individual history. What has gone on in your own brain and its consciousness over your lifetime is not repeatable, ever - not with identical twins, not even with conjoined twins.

Each brain is exposed to different circumstances. It's very likely that your brain is unique in the history of the universe.
