Asimov must be your favorite writer, or Hubbard. "Power failure" to the entire globe?? Did we forget how to boil water (steam)? Come into the light, dear sister, and accept the fact that we are more than we were. Once knowledge is released it's uses will be legion - for good or ill - and families will find ways to survive and prosper. The prophets of doom profit from your angst. They somehow always have enough yet always want more and they always fail. Look no further than Gore for our most recent example. Have hope. We will make it through.
