A Perfect Resurrection
A thought experiment challenges whether teleportation kills you and creates a copy.
Deep Dive
A LessWrong article explores a classic identity puzzle: if a person is perfectly copied, the original and copy are physically identical but have separate consciousnesses. This raises a disturbing question for technologies like teleportation: does it transport 'you' or merely create a new person who believes they are you? The author argues the subjective experience of the original is lost, making the copy a different entity, despite being a perfect replica.
Why It Matters
This philosophical question has real implications for the ethics of future technologies like mind uploading.
