I briefly thought that way, thought about it more, and realized that view of identity was incoherent. There are lots of thought experiments you can pose in which that picture of identity produces ridiculous, up-physical, or contradictory results. I decided it was simpler to decide that it was the information, and not the meat, that dictated who I was. So long as the computational function being enacted is equivalent, it's me. Period. No if's, and's, or but's.
When I've brought up cryonics on LessWrong [1][2], most commenters have said I'm being too pessimistic. When I brought it up yesterday at the Cambridge MA meetup, most people thought I was too optimistic. (I think it could work, but there are enough things that could go wrong that it's ~1000:1 against.) What makes the groups so different on this?
