It’s a classic philosophical thought experiment:
If, over time, you repaired a ship plank by plank so that no original planks remained, is it still the same ship?
Does it matter how long a new plank is on the ship before the next one is replaced? Once the 50% threshold is crossed, does it cease to be the old thing and become a new thing?
In our human bodies, we lose 500 million skin cells every day and they are basically all brand new after a few weeks. The cells in our bones are new after ~15 years.
Depending on how old you are, biologically, you’re not the same you you were.
So what if we consciously change things about ourselves? How does that affect this question?
At it’s core, this is all an exploration of identity, how we define it, and how durable it is or isn’t.
I have changed a good many things about myself over the years. Is there a point at which I stop being “Landon”?
