When are we not ourselves?

[GrandizerII]

No, I wouldn't.

This is somewhat similar to robvalue's VR thread, and thus my answer would also be similar. I would not because I am attached to the me that is currently typing this post, not to that other version of me who I would see as a separate entity from me.

But you are ok with the current you being replaced one atom at a time? The entity that typed this will be entirely replaced in a few years with a flawed copy that thinks it you.

At a time ... they're not all being replaced in one go. I would not call this dying or turning into a completely new self. The construction of self isn't really about the body anyway, it's a continual and ongoing process that is maintained through a stream of memories and perceived stability of the mind along with societal reinforcements of the supposedly unchanging self.
