An artificial persion asked me this very question, and below is what my artificial reply was:

We have lost the past. The past held onto practically everything including fun, excitement, Adolf Hitler, dinosaurs, the printing press, Adam and Eve, books, phonographs, cavemen, art, portable slaves, weapons of minuscule destruction, the Confederacy, morality, candle-lit hangings, iron maidens, typewriters, and bathing once a month.
