I'm aware that it's meant to be a reductio, but have read - I think - someone saying that QI is not much of a panacea just becasue we will often be horrifically disabled by the near death. So presumably QI does not mean that whoever dies in this world goes on to experience life as if nothing at all happened, even that the cat was never put in a box. So what exactly "survives" quantum immortality? Could it even "prove" that the dead (in this world) experience nothingness?
