I understand that in the next episode of Futurama, Fry will discover that the 93� he had in the bank 1000 years earlier has accumulated interest, making Fry a multi-billionairre.
No bank has an interest rate that exceeds the rate of inflation, however. It's very possible that a billion daollars in the future will be worth the equivalent of 50� today. Until Tuesday night, I can only speculate as to whether the upcoming episode addresses this.
