In a world where people can't be copied, it makes perfect sense to ask what you can expect to experience. In a world where people can be copied, you need to define what you mean by "you". It comes down to how your brain calculates probabilities, and whether it is using an appropriate algorithm in this new world where probabilities don't have to add up to 1.
