Kurzweil said there has been a 75,000 trillion-fold increase over 75 years.

Judge the numeric claim of a 75,000 trillion-fold increase in computing power over 75 years. True if a standard measure (e.g. calculations per second per constant dollar, or price-performance) over ~75 years supports an increase of about 75,000 trillion-fold (7.5x10^16), within the rough precision implied. Mostly true if the figure is off by a small factor consistent with a minor detail. Mostly false if a real but materially different figure underlies it (off by one or more orders of magnitude). False if the increase is wrong outright.

Set before the research began.

   “From 1939 to the present, we made a 75 quadrillion fold increase just in hardware. So it's 75,000 trillion fold increase.”

   “The conservative estimate of the amount of growth we made in software is about a million to one.”

   “So in 1939, we did 0.000007 calculations per second per constant dollar. And the last thing we did, 135 billion calculations per second. So that’s a 75-quadrillionfold increase for the same amount of money.”

   “No matter what type of technology we’re improving, we made the same shift in exponential terms every year for 81 years.”

   “Performance in constant dollars or in terms of labor units has improved since 1900 by a factor in the order of 1 trillion to 5 trillion, which represent compound growth rates of over 30 percent per year for a century.”

   “Around World War II, however, there was a substantial acceleration in productivity, and the growth in computer power from 1940 to 2001 has averaged 55 percent per year.”

The only sources giving the 75,000 trillion-fold figure are Kurzweil's own interview statements (E1, E3, E4). Those statements date the increase from 1939 to the present, about 85 years, not 75. In E4 he gives endpoints of 0.000007 and 135 billion calculations per second per constant dollar, and dividing one by the other gives roughly 1.9×10^16, not 7.5×10^16. The independent Cowles study (E6, E7) covers only the years up to 2001, reporting 55% average annual growth from 1940 to 2001 and a 1–5 trillion-fold gain since 1900, so it does not measure the full period the claim covers and cannot confirm or refute the figure.
