Let's see. 2^71 is... 2,361,183,241,434,822,606,848, or (thanks to number(1)) : two sextillion three hundred sixty one quintillion one hundred eighty three quadrillion two hundred forty one trillion four hundred thirty four billion eight hundred twenty two million six hundred six thousand eight hundred forty eight. A big hard disk is 1 billion bytes. A huge carousel is one trillion bytes. This is nine orders of magnitude larger. We'll get there, but not tomorrow, nor the day after.
