There is only one way to put yourself in the elite company of failed prophets, incorrect scientists and loony politicians:
Predict the end of the world.
To date, no one has successfully put a date to the end of the world.
To date, every person who has predicted the end of the world, has been absolutely, completely and irrevocably wrong.
In other words, if you are predicting the end of the world, and give a timeframe other than “at some unknown time in the distant future” your chances of being wrong are pretty much 100%. It doesn’t matter if your reason is scientific, religious or is counting on human intervention.
So, do us all a favor: stop predicting the end of the world, that is unless you have your own Death Star and are planning to use it.
