Homer was wrong in his assumption. If there however does exist a button, and it works, and there is no danger associated with ignorance about its internals, then there is nothing wrong with using the button. After all, someone put it there.

I in turn question one's competence when, instead of getting the job done, hours upon hours are spent on irrelevant parts of configuration or getting some ideal solution to work where something less elegant would perfectly suffice. Unfortunately, the folks insisting on 'mastering' ones tools tend to often be in that category.

As an analogy: I don't care if the craftsmen that fixes my house uses his hammer holding it upside down. I only care that my house is properly fixed and stays so. How that was achieved, I could not care less about.
