I remember back in 1999 some people actually thought the world was gonna end, among other things.
The thing I remember the most was all the talk about that "all computers will stop working" and that this would cause a total economical collapse. This caused the shops to advertise new computers as "year 2000-proof".
Personally I think if the world will end in our time, it will be caused by war and not by some ancient calendar.
