Dr. Neuman: One gene mutates and an ascomycete, uh, candida, ergot, cordyceps, aspergillus, any one of them could become capable of burrowing into our brains and taking control not of millions of us, but billions of us. Billions of puppets with poisoned minds permanently fixed on one unifying goal: to spread the infection to every last human alive by any means necessary. And there are no treatments for this. No preventatives, no cures. They don't exist. It's not even possible to make them.

Interviewer: So if that happens?

Dr. Neuman: We lose.
