While communicating accurately with people is an undisputed necessity, accuracy is not sufficient for a high-quality translation.
It’s an old truism that there’s more to translation than just replacing words from one language with words from another one and, along the same line, there’s more to a good translation than replacing sentences in one language with grammatically correct sentences from another language.
A good, high-quality translation needs to capture the meaning of the text in all its nuances and carry it across language borders.
