The dangers of teleportation

I’ve just started reading “The Emperor’s New Mind – Concerning Computers, Minds, and the Laws of Physics” by Roger Penrose. I don’t know a whole lot about the book — Penrose is a physicist, I think. (He also might be dead. The book was written in 1989.) — but my general sense is that it is an argument that there’s something about human consciousness that cannot be explained in purely materialistic terms. For example, you could not re-create a conscious human brain simply by using some magical device to wire up neurons you happen to have lying around so that they perfectly replicate an existing brain. I believe he’s going to argue that somehow the magical and confounding properties of quantum physics come in to play and are essential to create this mystical thing we call consciousness.

However, in the section of the book I’m reading, he’s contemplating the classic idea of Star Trek teleportation. The basic premise is that a person is scanned and the location of and relationship between all the subatomic particles (electrons, protons etc.) in his or her body are mapped out. This information is then sent to some other planet, where it is used to assemble a version of the person there. A purely materialistic view — the kind I believe Penrose is ultimately criticizing — would say that the consciousness of the person being reassembled on another planet should “arrive” undisturbed.

But there’s a kind of side issue here. By that process, you’re not so much teleporting someone as you are cloning them. After all, you’re scanning the person in the original location, but you’re not destroying them. This process would seem to lead to a potentially endless amount of duplicates of oneself. Penrose contemplates the procedure. (Page 28.)

Try to imagine your response to being told the following: “Oh dear, so the drug we gave you before placing you in the teleporter has worn off prematurely has it? That is a little unfortunate, but no matter. Anyway, you will be pleased to hear that the other you —er, I mean the actual you, that is — has now arrived safely on Venus, so we can, er, dispose of you here — er, I mean the redundant copy here. It will, of course, be quite painless.”

That Penrose… he’s a real card.

    Where do you find these books? I can barely make it through your blogs about them, thinking about reading them has me making faces like Joqain Pheonix in “The Master”.

    Did I spell his name correctly? He’s that guy . . . You know . . . That one. Yeah.

    They just played “Slow Ride” on the Radio. I’m going to find the bass player in Foghat and cut his hands off with a law mower.

    I think this book was recommended in some other book I read. I thought, “A book connecting quantum reality to the evolution of consciousness? Neato!”

    They should put that quote on the cover of the paperback edition – “A book connecting quantum reality to the evolution of consciousness? Neato! – Wil Forbis, Acid Logic Editor”
