Pete is clearly mildly perturbed by this, as so he should be: his faith doesn’t have much room for sanguinary magic, unless you count holy communion. - Charles Stross

“Not everyone is concerned with the deep future,” Manfred interrupts. “It’s important! If we live or die, that doesn’t matter—that’s not the big picture. The big question is whether information originating in our light cone is preserved, or whether we’re stuck in a lossy medium where our very existence counts for nothing. It’s downright embarrassing to be a member of a species with such a profound lack of curiosity about its own future, especially when it affects us all personally!

Vampires can’t exist. There’d be detailed records in the archives; they couldn’t possibly evade detection by the state for any significant period. Besides which...there’d be corpses everywhere. Human blood is a poor nutrient source; it’s about 60 percent plasma by volume and only provides about 900 calories per liter, so your hypothetical blood-sucking fiend is going to have to drink about two and a half liters per day. Those calories don’t come in the form of useful stuff like glucose and fat: it’s mostly protein from circulating red blood cells. Dracula would have to exsanguinate a victim every day just to stay alive, and would suffer from chronic ketoacidosis. The total number of intentional homicides for the whole country is around 700 a year; a single vampire would cause a 50 percent spike in the murder rate. Or they’d have to take transfusion-sized donations about two thousand times a year.

Bureaucracies excel at performing tasks that must be done consistently whether the people assigned to them are brilliant performers or bumbling fools. You can’t always count on having Albert Einstein in the patent office, so you design its procedures to work even if you hire Mr. Bean by mistake.
