Summary: it's probably been said before (and translated)
Sample quotation: "A good number of English-language detective novels, for example, have probably been translated into both Icelandic and Farsi... This means that John Grisham makes a bigger contribution to the quality of Google Translate's Icelandic-Farsi translation device than Rumi or Halldór Laxness ever will"
