You don’t need to wait for rebirth as this pretty much already is the case.

You are not the same person you were five minutes ago, or five years ago. Your body has replaced countless cells, your memories have shifted, your preferences have changed and the pattern of activity in your brain is different. There is no fixed, unchanging core that stays identical from one moment to the next. What we call “you” is a continuously updating process, not a solid object that persists unchanged.

There is no single place behind your face where a self sits and watches. Experience (consciousness) arises from vast numbers of neurons interacting in particular patterns. The sense of being a unified “I” is just something the brain constructs. It feels solid from the inside, but it is a generated appearance rather than a central entity.
