ChatGPT already works suficiently well in my own language (Danish). It can probably be improved, but so far it has worked well enough for several news stations to report on ChatGPT while prompting it in Danish. And schools are also worried about its ability to write essays in Danish, among other things.
I had some fun with it trying out a few Dutch dialects. Not perfect but it seems to be able to translate what it knows rather than rely on knowledge in a particular language only. Likeswise, it can translate programs to different languages. Paste some code and let it translate to Rust, kotlin or whatever.
