Productivity,
energy usage, and a number of other factors can all be approached as
a means of measurement when considering the rate of technological
advancement. Yet even these yield less than quantifiable results
because of the countless variables present in each. Productivity, for
example, might be measured by examining prices, the result of supply
and demand. However, supply and demand are influenced by an amalgam
of changing variables among a complex assortment of different
industries that fluctuate wildly in production levels. Another
approach to measuring technological advancement is to measure
processing power, but this, too, is flawed—while it is certainly
more quantifiable in itself, it can only be used to measure growth in
certain areas, such as information technology. Processing power has
little relation with other technologies, and cannot be accurately
used to determine increases in productivity throughout the world.
