Some people are not late to spout doomsday scenarios (Rick Wesson, the chief executive of Support Intelligence, a computer consulting firm)
If you're looking for a digital Pearl Harbor, we now have the Japanese ships streaming toward us on the horizon
It appears the Internet is just too unsafe for people and agencies all over the world."
