I don't really think you're correct on that one. To begin with, what makes us whole is mostly memories and our subconcious.

What makes it obvious are illnesses like dementia and general decay of neural activity as we get older.

If we implant the same memories into something or someone that person/entity would become you, like waking up from a long nap. You might not feel the same, think the same, or act the same, but it would still feel like you. Going one step further and growing an exact clone can probably go even further than that.

It's a copy with your memories, not you. Is one of them still you, if we make three copies?

they're also just you, but with a different derivative.

This is roughly inline with a many-worlds theorem where tiny variations can create many versions of you, this would be that but within the same universe.

Well, proving it would require you to end your life because the basis for the theorem is that there will always be a version of you that will not die.

		They're not you insofar as what's important to yourself in your attempt to live forever. Other people might consider them you. When I'm dying, I won't care at all about versions of me in parallel universes living on, because they're not me.
