Dunno why people are being creeped out so much, it has been proposed that one day soon processors will be mostly brain tissue that can resist heat very well, since silicon is starting to become less and less reliable to make faster processors, yes you can make multiple cores, but they reckon brain tissue would be able to process many times faster than a hex core can now.
Obviously it wont be 100% brain tissue as there has to be some form of chips for the sake of Mnemonics etc, only the tissue will calculate.
Now it's a dead rat controlling a robot for three months.
Next, it's a dead human controlling a robot for three months.
That's called a "zombie", the the truest sense of the word. A dead creature operating as if alive.
