Read the book if you're interested man. I don't know if he's right, but I think his arguments are interesting and at least worth considering. He argues that personal identity, and hence survival, don't matter. I think that's an interesting conclusion because it's contrary to what most of us think. If you're not willing to consider the argument it's no sweat off my back, I just made the thread because I'm still trying to figure out what I think about it and thought I would recommend the book to people interested in this type of shit.
