Nah. I can see the scanning procedure needed for whole brain emulation turning out to require some unspecified technology that's way too difficult for 21st-century science, or Moore's Law running out of steam before we reach the densities needed to do the actual emulation, but either one would be a Verne-type error; I can't see a category error on the order of electrical impulse => true resurrection happening unless we're very badly wrong about some very fundamental features of how the brain works.
