Many people here are more or less transhumanists, but I would bet that for a significant portion of the population, all these alternatives to death that you discuss (uploading, etc.) are actually even more frightening prospects than traditional death itself. For instance, many religious people who hope their souls will continue on would prefer death (especially if not too painful) rather than the horror sci-fi scenarios of being uploaded and traded to aliens to be kept in a zoo.
