Saying Mr. Yesterday will see B happen with 100% certainty is the truth but NOT the entire truth, Mr. Yesterday will also see A happen with 100% certainty because Mr. Yesterday has been duplicated, that's what people duplicating machines do. And that means today there will be 2 people, not just Mr. B, who remembers yesterday. Not everything is unitary, that is to say summing up all the probabilities of the possible outcomes of a event don't always add up to 100%. If I slice a orange in half and put the pieces in 2 boxes there is a 100% chance there is a orange object in box A and a 100% chance there is a orange object in box B. > > > However, you could not have known, because what each copy experiences is > irreducibly random.

Mr. A will see A and Mr. B will see B. What more is there to say? What exactly have I failed to predict? And by the way, if a omniscient oracle can't answer a question that can only be because it wasn't a question.
