    This is a cool thought because it’s not about being copied but more about the Ship of Theseus.

    Why do we sleep?

    “The body needs sleep.”

    No, the body needs rest. Our physical self just needs down time and relaxation and then it’s good to go again. Our BRAIN needs sleep. Specifically, REM sleep to process all the new data that was taken in. Converting short-term memories into long-term memories. Sorting and organizing data. A kind of hard drive defragmentation.

    Our sleep is normally presented like a sine wave. We regain base level consciousness cyclically several times a night, which is why we dream. Which is why our dreams are usually tied to recent memories. The more good sleep we get, the more our brains can deal with recent experiences.

    When we wake up, it’s like rebooting a device after an OS update. It’s us, but with altered software. We are as much the person we were yesterday as the Ship of Theseus is still the Ship of Theseus after having pieces fixed and replaced. The whole is who we are, not the bits that changed.
