Hey reading the IC, for Casper if he replicated a device like his phone or his Playstation, once he goes back to the original won't it not have anything that he did on the replicated version? Like game progress or recent call history or anything?
If Casper plays a replicated version of his Playstation, nothing will be saved on his original one. Once he copies something with a memory card, everything on that memory card will exist within the copy. However, nothing done with the copy will ever affect the original.
Once the copy vanishes, he can replicate a new phone or playstation, if he does, the replica has the same information saved on it that the original did. The previous replica doesn't exist anymore, along with anything that was saved on it.
