There are at least two plausible reasons why otherwise rational people spout lurid doomsday scenarios instead of focusing on the mundane, technical, and challenging problems of networked information stores. First, and most cynically, they can make money from doing so. Kaspersky runs an Internet security company; Clarke is a cybersecurity consultant; former NSA director Mike McConnell works for a law firm that sells cybersecurity services to the government. I think there’s something to this, but I’m not ready to accuse these people of being venal. I think a more likely explanation flows from Paul Ohm’s Myth of the Superuser: many of these experts have seen what truly talented hackers can do, given sufficient time, resources, and information. They then extrapolate to a world where such skills are commonplace, and unrestrained by ethics, social pressures, or sheer rational actor deterrence. Combine that with the chance to peddle one’s own wares, or books, to address the problems, and you get the sum of all fears. Cognitive bias matters.
