youre not wrong in that cloning you twice would immediately create 2 distinct entities. and their consciousness/brains would immediately differentiate. so? now theres 2 of you.
i dont see the problem with there being 2 versions of you instead of the 1 that was destroyed and recreated in a transporter. its the experience that makes the differentiation, and if there is only 1 of you at a time there is no differentiation. only one of you continues experience, there you are.
