*Yes, but that doesn't mean they aren't all "you". If 5 very distinct
persons have different memories and even personalities then obviously they
have become five different people, however that differentiation did not
happen at the instance of upload, that happened later after the 5 brains
receive different input information from their senses. *

*The principle that all 5 still remember being you yesterday means they are
all "you", it also means that because none of them remember all the things
that happened to the other 4 since the uploading occurred they are no
longer each other. *

*If all this seems very strange that's only because today people
duplicating machines do not exist so we are not used to dealing with them,
but we better learn to be because they are coming much quicker than most
expect. Unlike time machines or faster than light travel, there does not
need to be any breakthrough in science for people duplicating machines to
come into existence, all that's required is improved engineering. *
