No one has a good answer to that. But it's not necessary to answer that to conclude that whatever task a human can perform can be replicated by a sufficiently complex algorithm.
You also haven't really made any good-faith effort to read the neuroanatomy textbook I tried to suggest to you in another thread.
I did look for it yesterday but wasn't able to find a free version. Neglected to mention it because I was unable to comment (that restriction seems to have been lifted). I am genuinely interested in reading it.
