In media, there are sometimes stories where a person is cloned/duplicated (usually with identical memories) and the clone is murderous towards the original. Usually it’s something like “I knew there could be only one of us, and you would do the same”. Sometimes, they’re able to work things out and can share a single public identity, or duplication gives one copy a chance to do go off and live a new life that they always wanted.
How would you and your duplicate get along? Assume you are living like you do today, in a society where duplication is unheard of and has no legal precedent.
So I’ve been thinking about this and I think it mostly depends on if my wife was also duplicated. If so, I could see the 4 of us living together and pooling resources. Possibly even working out some shenanigans to double dip or get out of some things. However, I can’t see my wife or myself being cool with an arrangement where a duplicate and I share my wife. I don’t know if I’d kill The other me over it but, I could see us coming to blows over it.
