I disagree. As a programmer I can represent inputs and outputs as text and write code to do intended transformations. As a quick ad hoc test I can easily knock up a shell pipeline to give confidence in those results, even if it would be too slow for production. There's many occasions when powerful shell usage is quicker to write than Python, etc.

My comment in reply to http://www.iheartchaos.com/post/16393143676/fun-with-math-di... is one example.
