@davidgerard a reasonable conclusion seems to be that unless explicitly stated otherwise, assume by default that it was probably assisted by some LLM.

@rauschma for me, German is "second language" by a very thin margin...
Things get confusing when you are born in one country, grow up in another, live on a site with a third language in active use, your parents natively speak one language but have been using another on a daily basis for years.
It seems that many implicit assumptions of many (monolingual) native English speakers start falling apart at that point.

@rauschma I had to check the definition of "native language". Conclusion: By the literal description as given by dictionary.com, German does qualify as that. However, given that it is also considered synonymous to "first language", I am not entirely sure what the actual intent of the dictionary editor was, as I would not consider it my first language...
Generally, the use of the terms "native language" and "first language" in English seems very fuzzy and ill-considered.

@ered @annasdtc pretty much this.
Compare how e.g. the book shop business has been squeezed by the likes of Amazon, and partly in a reaction to the resulting dysfunction of the market, some authors have taken to self-publishing. In a properly functioning market, an author shouldn't need to run their own publishing house and book shop.
