A translators cannot necessarily interpret and an interpreter cannot necessarily translate. Moreover, there is no such thing as 'simultaneous translation' or 'written interpretation'. Stop complaining about translation and translators or using them as scape goats. Translation is a multifaceted process involving many people, not just the translator. Moreover, many of the problems people complain about in a translated text cannot be solved without giving the translator permission to rewrite the material in its entirety.
Translation is more than just swapping words or converting a phrase from one language to another.
And while I certainly don't want to exonerate all translators for every error ever made, let's consider the big picture before dumping on the translator. See the value and relevance of translation. Translation is about communication. In the modern world, often called the 'global village' or 'international community', communication of information and ideas between different languages and cultures is critical for peace, for the development of economies and technology, and for the growth of nations and regions. Translators are a small, but vital part of this process.
