Carl Sagan claims awareness arises through complexity. A sufficiently advanced computer should be able to become self aware. But on the other hand I know a few folks out there claims it takes little more than a few trillion connections and a fast enough graphics card, it takes a little something called a soul.
Now I don't believe in that voodoo hogwash that my consciousness is sitting comfortably in my soul gland controlling my morals. But until we can replicate billions of years of evolution into a computer, all we are really doing is building faster calculators (And super internet porn machines, again not that I'm complaining).
Heres a though experiment that I like to run by people:
Lets say that some smart fellow builds a teleporter that recreates you cell for cell even atom for atom. If a machine could create and exact copy of every neuron. Would that copy of you have all of your same memories, emotions, and intellect? Or would you just be left with some mentally handicapped bag O' flash, that looks just like you? Because something other than just the right neurological connections create who you are.
Basically humans are just meaty machines, our brain even has several similarities to computer in how it processes information. What I'm getting at is will singularity happen if we build a fast enough machine? Or does it require something more we haven't wrapped our heads around yet? Like a soul (Or an equivalent scientific explanation)?
