A potential error for the second conclusion is that we have incorrectly predicted the nature of consciousness, and the true solution is that one is somehow able to perceive without a physical avatar functioning in the way we expect of a human capable of perception. Thus, "you" are able to experience the branches of the MWI where everyone else perceives you to be dead.
I had an incredibly frustrating conversation this morning trying to explain the idea of quantum immortality to someone whose understanding of MWI begins and ends at pop sci fi movies. I think I've identified the main issue that I wasn't covering in enough depth (continuity of identity between near-identical realities) but I was wondering whether anyone has ever faced this problem before, and whether anyone has (or knows where to find) a canned 5 minute explanation of it.
