Query: I hope those that bought this book have learned something!

I bought this book a year ago to find out what I was up against when trying to deprogram a friend who had the heck scared out of him by Y2K. After looking at the book for an hour and realizing it was based entirely on conjecture and scare psychology, I sent it back (very thankful for Amazon's generous return policy). This book no doubt mostly appealed to paranoid people who were already distrustful of technology. Now that the event has past and nothing of note happened, I am sure there will be a new crisis some budding author will wield to manipulate this same sort of person out of their money. If you were duped once, please don't let it happen again by falling for the "insurance" argument used by this author (be prepared "just in case"). Remember, if the premise is unsubstantiated, it is not logical to act upon. One could make the same, equally "plausible" argument about preparing for an alien invasion--just in case.
