Exactly, that's why different languages can spawn different communication. Certain things cannot be translated, whether they are idioms or grammatical constructions. It's not just "sad", it means a unifying and, in some case, simplification of thought. Now, with English becoming more dominant, I guess it depends on your background and ideas whether this reduction to "things that can be expressed in English" is a good thing or not. I pick English here, because it is the most obvious example given international trade, travel and the internet, though the same applies for various big, hegemonic languages in their surroundings, and the same happens with dialects even within a technically mono-lingual environment.
