Terrorists unleash lethal chemicals in a Japanese subway. Insiders steal weapons-grade uranium from a Russian Navy base. Four different American soldiers, certified as reliable for nuclear weapons duty, suffer deadly mental breakdowns at a single U. S. Navy base within a single year. As these recent events demonstrate, the intersection of high-risk technology and inevitable human error can result in the very disasters our machines are designed to prevent. Lloyd J. Dumas's terrifying book chronicles past and potential calamities to shock us out of the complacent belief that we are safe in the hands of technology. From terrorism and nuclear accidents to computer viruses and power blackouts, the entire landscape of our technological culture poses the threat of swift and sudden destruction. This book may keep you awake at night and cause you to regard your computer with newfound distrust, but it also provides a sorely needed common sense approach to risk assessment in a world fast evolving beyond our control. Dumas presents what he calls a "calculus of catastrophe," an intelligent and aware evaluation of the disasters we can foresee and prevent, the risks that are too unlikely to worry about, and even the technologies that are too hazardous to warrant their use. Lethal Arrogance sounds an urgent wake-up call to put mind over matter and exercise human judgment over technological dominance.
