There are plenty of situations when the human sense of nuance and appropriateness is absolutely necessary. Translation of legal documents is at the extreme end of this (for example, when my Brazilian wife had to translate her university diploma into English upon moving to Sweden.) If you just need to get the basic gist of something in a different language, then machine translation is obviously more performant.
