It's fine if everyone realizes they are rough sketches, specs, or prototypes. But programmers have hubris, developed through many years of writing shitty code they have to burn to the ground. Other professionals often don't have that hubris. The power of writing code goes straight to their head. Programmers are trying to write the least code possible to do what they need to do, because they know every single line is a liability. A company liability, and a personal liability, because they're the one that will have to fix it when things go wrong. I think people who are not programmers don't always understand that, and they are extra isolated from it because ultimately they don't maintain or fix their stuff. Some other poor soul does, so out of sight out of mind.
