Does society's increasing complexity make us more or less susceptible to catastrophe?
The answer is probably "Yes." There are factors that make us more susceptible to disaster (witness what happens when one element in a just-in-time manufacturing process breaks down: the whole thing grinds to a halt). But others seem to make us more resilient (like the fact that millions of people now know more about computers than the brightest computer scientists of 1950, thus being better-armed to solve complex problems than ever before). It's worth taking a look at how prepared we are for catastrophic risks, but we shouldn't just throw in the towel because of fear.
