Picking the exact date for the end of the world, without scientific evidence to back you up, makes you a fool. Harold Camping was a fool, and unscrupulous and foolish media gave him a spotlight he didn’t deserve. With the exposure, he cheated a lot of foolish people.
It is a little depressing that professional media get swept up in ‘end of the world’ predictions from nutbars, and ignore accurate, scientific predictions of destruction. Where is the fame for predictors who get it right?
