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.
I don’t think I’d kill me. I think it would be cool for one of us to commit a brazen crime in broad daylight whilst also having a rock-solid alibi. I couldn’t have killed that person; I was giving a speech to 100 people at the time who can all testify for me. Give detectives etc a real head-scratcher when all the evidence points towards me being the culprit but I was also undeniably somewhere else.
I’m picturing me and my duplicate having a fight that devolved into us actually trying to kill each other over this because honestly, I’d rather shoot a man…no scratch that, I’d rather BE shot than give a speech in front of a significant number of people.
