Jack Woehr, Dr. Dobbs, How Important is Numerical Accuracy? here. I guess FaceBook and Amazon are the only computations that matter. Rough realization for a Turing Award winner for numerical computation.

WK: Most numerical computation doesn’t matter. I know that sounds perverse, but in my experience, looking over the shoulders of other people, at least nine-tenths of what they compute gets thrown away, much of it without ever being looked at. They have only to get a glimpse of something to realize they never should have computed it in the first place.
