When Worlds Collide

People were over tonight and there was much watching of Buffy. I experienced a severe mental crossover between it and Guns, Germs and Steel, which continues to dominate my thoughts. What happens when vampires finally domesticate humans? Given the apparent low population density of vampires, it isn't too surprising that they haven't been able to yet. But once they do, they'll be able to move from being hunter/gathers to sedentary farmers. That will allow the development of all kinds of technology that wandering nomads just can't support, such as writing, pottery and metallurgy. The surplus of food will support specialty occupations like craftsperson, soldier and bureaucrat. Large scale political organizations will emerge, allowing for civic construction projects and conscription for armies of conquest. Living among their livestock and waste, they will also develop new crowd diseases. While this will slow their population growth some, it will equip them with biological weapons to help defend them against colonization by foreign vampires.

So the obvious question is, how can we keep ourselves from becoming domesticated?
