That'd make more sense, I guess. It's like that old thought experiment my Master told me about, with the teleporter that just kills the original and creates a perfect copy somewhere else.

Even so, I know it's theoretically possible, but it doesn't seem practical to do it on so large a scale. Besides, if you could scan all of someone's physical properties and mental state, wouldn't it be a hell of a lot cheaper to just run a computer model?
