There is no “your consciousness” as an identity across the two copies. So you fork a process and you kill one of the processes. That process experiences death.

There is no “your consciousness” as an identity across the two copies. So you fork a process and you kill one of the processes. That process experiences death. Likewise one copy experiences death. Does it matter? Depending on your objectives. If it’s to achieve some sort of world domination through pseudo-immortality, probably not, since your copy will execute faithfully as you. But your perception, the body unit you’re in, will most definitely see an end. It won’t ‘jump’ into the other medium. This you will die. That you will live.
