Any system that involves humans is inherently of staggering complexity. An example. twitter 
GeePaw Hill relates this experience.
quote
My daughters, one of whom lives in our odd-shaped duplex former group house with her family, one of whom is just visiting for a month or two, commented on me going to stand out on my deck and sing to the trees.
Everything they said was positive, even glowing. They say they *love* it when they hear me doing it.
This being noticed makes me shy.
It makes me hang back. It makes me select my times and my material.
I did not anticipate this.
I am still working through it.
Not wanting to "lesson" here. I still don't know what I think or feel about it.
But I can easily say this: any system that involves humans is inherently of staggering complexity, a million miles far beyond anything a mind, an abstraction, a method, a logic, a language, can hold.
