I remember learning in my machine learning class that translation is a solved problem. However, the reason it appears to be bad is because it is computationally expensive. There are different levels of translation, each of which are increasingly more difficult to compute. There is word for word translation. As you can imagine, this is the lowest level, easy to compute, but overall has poor quality. First, word for word translation, then syntax translation, semantic translation, and finally interligual semantic translation. I took that class a while ago, so forgive me if I'm not 100% accurate, but that is generally the issue: the higher level translation you want, the more expensive the computation.
