Especially if it can be done real-time and according to the context/level of the audience/listener. Even within the same language, translation from a more technical/expert level to a simplified summary helps education/communication/knowledge transfer significantly.
That is an intellectual exercise, it requires understanding, and I have not yet seen an LLM implementation that does it properly. If you know one...
What I have seen are outputs that can give the illusion of a properly done job, if the user were willingly (or not) blind to quality.
So: non intellectual translation, we already had tools; intellectually valid one, then we would have much higher opportunities than translation.
