Large systems are almost impossible to create and maintain. Imagine that we could build dog houses and, if we're careful, houses, but nothing bigger that wasn't under constant threat of falling apart? Imagine news headlines of "Chartres Cathedral collapsed again today." And then imagine a response of, "Well, that's because it's hard to build."
What Dr. Kay said, and I'm sure he only backed off of it because it's tiring making these arguments over and over again to people who look on with open mouths, is that there is the equivalent of the arch waiting for us. You, Dave, may not believe it. You may say anyone who complains about houses falling in on themselves just doesn't know it's hard work. I'm saying it's hard work to make them out of toothpicks and dental floss.
The reason I get annoyed in my comments (and had to apologize) is that I've spent 15 years working on a solution and have had nothing but resistance from those who can't see past the state of the art.
You have no sympathy for people who aren't constantly improving themselves. I have no sympathy for an industry that isn't.
