> Some words just don't have a translation in other languages. Generally speaking I'm inclined to agree with you but you chose a bad example. The earpieces could translate it as "time to eat!" or "thank you for the food.". It's not a literal translation of course but a lot of the work involved with translations is about finding the right substitutes for these kind of phrases. In japanese there's a lot of mundane phrases that could better illustrate your point, for example how would an earpiece translate 好きです。 as a stand-alone phrase? It could do so literally but it would probably sound very unnatural. To do a natural translation the device would need to be understanding the conversation as a whole and that would be way more difficult to implement since it will involve some actual intelligence :)
