I think the real reason is that in order to fully learn a language one has to absorb the culture it's used in. I appreciate because i'm slightly multi lingual. Elegant words in one language have no good parallel in another and an ugly approximation must be used instead. Also, what sounds pleasant in one language can sound artificial and stilted in translation.

I recently tried to translate such heavily culture-embedded texts into English so that they stay funny and rich, using GPT-4, and it did an almost perfect job there. Much better than any other translation tools.

You can dictate the style of writing in your prompt, though. For example, I have a few prompts saved in my notes, each for a particular use case. Except for a few comments I write on social media (like this one), none of my English output is generated directly by me, and it never looks or feels generated by AI. All thanks to the writing-style prompts.
