There's a great tale by Nasreddin, a turkish 13th century philosopher. The tale was about him making a bet with a sultan: he would teach one of his donkeys to talk in 20 years. If he won the bet, he would be rewarded with a chest of gold, but if he lost, he would be beheaded. When his wife asked him why he'd make such a frivolous bet, he replied: In 20 years, either I will be dead, the donkey will be dead or the sultan will be dead. In other words: the longer the timescale of your prediction the more meaningless it is. If you aren't even around to see the results of your prediction or bet, then it's already meaningless. Knowing how bad people are at making long term predictions makes it an even more pointless debate. Why not 130 years? Or 120.005 years? Or 1000.
