If you clone yourself, would it be you or a different person? How to define "me"? Let's say consciousness is an ability to perceive yourself as an independent unit of the whole system. I can feel myself. I can't feel my clone. So it seems my clone is a different person. Though, this person has the same configurations, such as goals, memories, life principles, and so on.
We can define "me" as a set of some factors, like a memory net, which is expressed as some tricky data type. Set of goals, and other things that make you who you are. Thus, "me" = a function that denotes a combination of the factors, e.g. A x B x C.
I alter my views, goals over time. The function now returns a different checksum of me. Will I be myself tomorrow? It appears not exactly you. Though I save my fundamental views and anchors, tiny processes are going on right now which alter the fundamentals.
