*takes a deep breath*
I am bilingual German/English. Born German, writing mostly in English. I sometimes translate my own stuff.
I have seen AI translations. Even human-edited AI translations.
They are - forgive my frankness - utter crap. An AI cannot capture the nuance, the connotations and the expressions of the target language.
It can only take the source language's words and turn them into target language words.
Working as editor with such a translation is a horror trip.
