That's the point. At no time did the engineer building the application make a poor choice. He/she made the logical rational choice to get the job done. It's the same thing for the tools developers. They each made their respective tools to solve a real concrete problem and succeeded. The problem is that everyone seems to be making incremental improvements and engineering choices that locally make sense, but when you zoom out and look at the whole picture things look absurd. We're incrementally improving ourselves to a local maximum that seems to be an uncomfortable place to be. There may be a better path that will lead to a better maximum, but we can't see it from where we are.
