Crazy that people are downvoting this. Copying a consciousness is about the most extreme violation of bodily autonomy possible. Certainly it should be banned. It's worse than e.g. building nuclear weapons, because there's no possible non-evil use for it. It's far worse than cloning humans because cloning only works on non-conscious embryos.
It might be one of the only reasonable-seeming ways to not die.
I can see the appeal.
Violation of whose bodily autonomy? If I consent to having my consciousness copied, then my autonomy isn't violated. Nor is that of the copy, since it's in exactly the same mental state initially.
