TLDR: Everyone always attributes it to JWZ, but it was actually coined by David Tilbrook. It's not mentioned in the blog post, but David told me in 2007 that he said it at a EurOpen conference in Dublin circa 1985. David also told me this is only his second favorite quote; the one he was most proud of, from 1981, was: "Software is the only business in which adding extra lanes to the Golden Gate bridge would be called maintenance."
