Excellent points. An example from a different perspective - the differences in potential interpretation between languages. I experienced this ambiguity early in my engineering career when one of my first assignments was to translate a feasibility study from English to French (junior engineers sometimes have to take what's dished out). I was amazed at how imprecise the English language version was, while nevertheless appearing valid and thorough - French simply doesn't permit the kind of slipperiness of expression which English does. As you can imagine, it made translating the text an interesting challenge, as I had to track down the precise meaning of some tricky paragraphs through discussion with the senior engineers who felt they had crafted clear work. Imagine a young female engineer challenging these senior, globally respected male engineers, telling them to express themselves better!
