The Warring States of NPF - Zombie Apocalypse: Not Just Possible, INEVITABLE

It's still stupid though. Even if zombies were the healthy active rage-virus kind from a souped up mad cow disease, they'd all be dead within 2 weeks, tops!

5 Parasites: The fact that your average human immune system in well developed countries is able to have over a dozen viruses and parasites in it at any given moment and still be the picture of health doesn't necessarily make me scared of one that's already been in us for a long time, and so far has only lightly been linked to schizophrenia, and has already been theoretically cured by conventional psychotic medicine. Though they are talking about a vaccine to be created to prevent schizo from even developing from toxoplasmosa gondii, I dunno if it could improved to make coordinated, or deadly behavior beyond the strong desire to be around cats...

4 Voodoo/Neurotoxins: Not actually a zombie, just a really drugged person. Drug him into a high-coma, (it's like death!) and when everyone thinks he's dead let him wake up from his stupor and keep him lightly drugged to do your bidding. You see crack addicts and the like and the crazy things they do for their stuff, and the crazy things they do under suggestion, it's very similar. The story of Clairvius Narcisse actually states that once the drugs wore off, Mr. Narcisse was fine. Of course, the actual truth of the story has yet to be proven.

3 Rage Mad cow: The insane symptoms of Mad Cow are not directly caused by the disease, but by the brain damage it causes, meaning no one can make a super mad cow disease to turn us all super-bloodthirsty for any actual purpose, and the fact it doesn't transmit by saliva or by blood (aside from direct blood transfusion), and may not even actually be transmitted by eating the dead that have the disease (unless they were human) A serotonin blocker would be pretty nasty but would have to be pretty wickedly designed by man and feature both easy infection and slow in it's dehabiltation, because otherwise the victim would suffer from severe exhaustion pretty quickly.

2: While it's the most farfetched I've seen, an unthinking, motor driven organic zombie workforce would logically cost more and be less feasible or effective as a robot/android workforce, based on cost of feeding, lack of any advanced technical skill beyond the most primitive of impulses, and the cost of the medical procedures used to reanimate. So Zombie Revolution loses this round, but Robot Revolution gains gets yet another...

1: Nanobots: Despite popular media depictions and whatnot, it seems to me that the body would treat nanobots like any other invader, and destroy them fairly easily as nanobots are built from organic stuffs. Still mostly theory anyway, and effectiveness outside their sterile petri dishes is in question. Also, until they can make supercomputers with strands of DNA (still in development) nanobots that are utilized for a very complicated process (such as: Kill that person, or just plain Kill!) would have to have an equally complicated command structure, one that could not yet be innately programmed into the nanobots themselves, until previously mentioned tiny computers the size of dna.

Until then, there'd have to be some sort of command hub to send out detailed messages, and all us survivors would have to do is find it, block it's signal, or blow it up.

The most realistic is the Voodoo/Neurotoxins (they're already doing it! Don't you want a caffeinated drink and a cigarrette?) Least realistic is the Nano's, Least practically applicable would be reanimated flesh, which would be useless for most people until we learn how to preserve the minds, and live forever. FOREVER!
