We already phisically change completely every few years.

We still don't know if we stay we or become something different.

Experience says we are not the same person we were and we often feel disconnected from who we were or who people that know us think we should be.

From our perspective we just accept who we became and simply remember who we were, without being able to be that person ever again.

That is not true at all. Please don't perpetuate these old wives' tales on HN.

A lot of your cells do die and are replaced, sperm cells for example have a life span of 3 days, white blood cells about a year, but brain cells (especially relevant to the context of this thread) are with you for life.

Much of Buddhist philosophy (the "doctrine of no self") is build around this train of thought...

My thinking is, my brain is almost entirely what makes me "me". The rest of my body is just a container. I do understand the analogy though.

Sense of self is quite possibly an illusion a bunch of separate processes in the brain use to organize things. If this is true, changing some of those gradually enough will preserve your sense of self. This is what any experience does to you in various degrees. (Changing them rapidly might conflict with previous memory though.) Even remembering something rewrites that memory and you end up with a slightly different one.

So it is possible that not only your body gets completely replaced many times over, but your identity and memories and thinking processes get replaced by imperfect copies.

That just means that the brain is the entire ship. All the same questions still come up

This feels analogous to reassigning properties on an object.
