From President Bill Clinton's recommended reading listPublishers Weekly BestsellerWarnings is the story of the future of national security, threatening technologies, the U.S. economy, and possibly the fate of civilization.In Greek mythology Cassandra foresaw calamities, but was cursed by the gods to be ignored. Modern-day Cassandras clearly predicted the disasters of Katrina, Fukushima, the Great Recession, the rise of ISIS, the spread of viruses and many more. Like the mythological Cassandra, they were ignored. There are others right now warning of impending disasters--from cyber attacks to pandemics--but how do we know which warnings are likely to be right? Through riveting explorations in a variety of fields, the authors--both accomplished CEOs and White House National Security Council veterans--discover a method to separate the accurate Cassandras from the crazy doomsayers. They then investigate the experts who today are warning of future disasters: the threats from artificial intelligence, bio-hacking, malware attacks, and more, and whose calls are not being heeded. Clarke's and Eddy's penetrating insights are essential for any person, any business, or any government that doesn't want to be a blind victim of tomorrow's catastrophe.
