And I Feel Fine

For everyone confidently assuming that the end of the world types will now slink away in silence I point you to a Wikipedia article on The Great Disappointment. That was a big 1844 prediction of the end of the world by a somewhat similar preacher named Miller. Yes, afterward many of the followers fell away, but a new movement arose called The Seventh Day Adventists who are still with us today. For that matter there are the Jehovah's Witnesses who have predicted the end of the world so many times it could be a Saturday Night Live running joke. And among the modern money grubbing ministers who can forget that Pat Robertson has been wrong pretty much every single time he has predicted anything and he still gets massive donations.

No, these people are not going away because the end of everything whether predicted by a religious or secular authority makes everything so much simpler for believers. They will just regroup in another area and never admit they were wrong.
