manufacturing process improvement and scale up production cause cost to fall the same often happen in the world of service,
people work the bugs out of service innovation to the point of providing near-flawless delivery. again the performance cost of the new technology improve with time and investment-typically slow in the beginning, but gaining speed thereafter.
at a certain point, the new technology matches its older rival in performance and/or cost feature. but unlike the establish technology, the new one plenty of opportunities for continued improvement. if all goes well, it will improve to the point that its older rival will be displaced from the main marketplace.
this reversal of fortunes describes the observable plight of chemical-base photography today as if face the challenge of digital imaging. barring some technological breakthrough, the major opportunities for film improvement have been exploited. those that remain will be costly and difficult to implement. meanwhile, digital imaging can look forward
