Millions, Trillions, Billions, ...

When I was a kid (40 years ago), the NYSE traded 13 million shares per day; the US budget deficit was measured in billions of dollars and the budget debt was hundreds of billions of dollars.

Now, we have multiplied these quantities by 100; they are measured in billions, hundreds of billions and 10+ trillion.

Will we be talking about quadrillions in 2060?  What about the 24th century (in the Star Trek era)?  I suppose if "things" increase by a factor of 100 every 40 (actually, let's say 50) years, then in 2363, we'll be talking about ...

1E13 (2012) --> 1E15 (2062) --> 1E17 (2112) --> 1E19 (2162) --> 1E21 (2212) --> 1E23 (2262) --> 1E25 (2312) --> 1E27 (2362)!

1E27 is

1,000,000,000,000,000,000,000,000,000,000

I predict the US National Debt will cross 1 nonillion dollars in 2362.  Prove me wrong!  Go ahead!
