What is a continuous stream. I was knocked unconscious for a few minutes in 2007 when I came off a bike. Am I the same person today as I was in 2005?

On the other hand dementia eats away at memories and personality. My grandmother doesn’t remember having children (who are now in their late 70s), a husband (she had two), but does remember (mostly) life as a child. She wasnt unconscious though.

(It’s basically the inevitable same end game as the rom com “50 first dates”)

As you say it’s philosophical - a bit like Triggers Broom. Or 1 minute Time Machine in a way.

I like the answer to ship of Theseus (define the ship by the keel or whatever), If you were to replace every cell in your body are you still the same person? That happens multiple times over your life. What if you were to replace some cells with non human parts - a false leg, a pig heart. When do you stop being “you”

If you replace every neuron in your brain with a synthetic neuron, one at a time, a there a point you no longer exist. Is it a continuous reduction. What if those neurons are put together elsewhere, which is you. Both? Neither? A fraction of each?
