Ok, I'm going to quote you from a previous post you made because I think it's important.

I'm not exactly sure what my question means but I think what I'm asking is -- the human brain is always sensationalised as being the most complex and (one of) the fastest 'computers' on earth

The human brain is not sensationalized that way. That's you doing the sensationalizing. Computers are on an entirely other level.

The human brain has a lot of connections which allows it do do many different things, it's still slow as hell though. Biological processes are inherently slow. Computers do not have that same limitation. It isn't even a matter of redesigning computer chips so that they can act like the neurons in a human brain (although that might help). It's about designing software that performs the operation indicated. How do you tell a computer how to identify a cat in a picture. Currently the process is to give it a bunch of examples, use pattern matching, and give some answer based off of a percentage. The field is still being researched, we hardly know enough about how the human brain works in the first place to design a piece of software that emulates what it does.
