The brain is the oldest computer known, developed through a process still undetermined in millions of years. As I see it now the brain is developing a computer to the level of A.I. (interesting). The brain needs information to function such as eyes,smell,taste,touch,hearing as forerunners (stimuli) including many below the conscience level interacting together with the brain comprising functions many of which are not understood or discovered yet. To use the wet brain as a natural computer one would have to use what the brain already uses for incoming information, which by the way is already been done by attaching probes to fingers,etc.etc. It is only a matter of time when computers will function with the brain (with safe guards of course) enabling human beings to become whatever they wish to be. I see in the future software unlike the ones for computers which function with human brain information that it understands. Meanwhile critical situations exist with the human brain and mind as well,until those are answered perhaps the best thing for now is non-human A.I.
