Ship of Theseus was a description of ourselves. We are BOTH the same and different, simultaneously. Your body's cells are in constant renewal. It's not 7 years like the aphorism goes but at different rates. Nevertheless, you're not the same you were were even a moment ago but certainly not the same you you were years ago. Quantum states constantly flip and change. Impractical to be recreated precisely moment to moment. [the length of a moment in this case is rate of change - too fast for us humans to deal with] You're still you but you're also not you. Such is life. I don't think this will change with quantum teleportation. It's just a different way to reconstitute. We're always reconstituting on an ongoing basis. You're you and not you. Ship of Theseus.
