Dutch is a low-hanging fruit though, ain't it? Closely related Germanic language with heavy English influence post-war?
edit: To make the implied question explicit, I guess it might do well on other similar Germanic languages (say Norwegian) but struggle beyond that? Or?
Isn't it only a matter of languages of the input that the model was trained on?
If we want it to spit out Klingon, I'd have to be trained on Klingon input, no?
