Downloading the Brain
Monday, May 23rd, 2005Every now and again, “downloading the brain” pops up in the news media and it leads to some confusion. As it’s portrayed, somehow you, the person reading this, is transfered into a computer, leaving an empty shell (your body) behind. That’s not true. Instead, a brain download would be a copying of you being created on a machine. You, the you reading this, would still exist in your body and the copy of you that exists in the computer would also exist. There was a short story in “Gödel, Escher, Bach: An Eternal Golden Braid” (or “The Mind’s I“, I can’t remember which) in which this brain download scenario occurs. Both versions of the participant are fed identical inputs, but at some point the computer version deviated from the flesh version, resulting in a different “being” with different thoughts and different perceptions. That is what would happen to you if you were copied into a computer. The duplicate would start thinking on its own, making decisions based on it’s experiences, different from your own. Immortality wouldn’t be achieved and you would still die, leaving behind a divergent duplicate of yourself different then who you were when you died.
