I'm not satisfied with the real world, but, as Eliezer says, this has more to do with me than with the rest of the world. Unlike the hypothetical person described in this post, however, I don't expect that any of the fantasy worlds that I read about in novels actually would be any more satisfying. I really don't know what would make me satisfied over the long run, short of hacking my own brain, or, perhaps, getting a cat. ;)
