This is the sort of attitude that is responsible for the proliferation of "cargo cult" style programmers. People in industry who don't understand anything at a deep level and barely understand what and/or why they do what they do most of the time. They just find code -> paste code -> tweak here, tweak there -> quick test -> move on. Now you have systems which contain massive technical debt and are not well understood or designed. People like this view everything as a black box.

No, no thanks. I work in the medical device industry, but this applied everywhere. If you don't understood your tools at a deep level please, study. Go off and write some trivial stuff before you infect important systems with your ignorance.
