Hard to decide the appropriate level of outrage here. The authors seem to be aware of how chatGPT works and how this would produce inconsistent results and falsehoods, especially in languages with a smaller corpus. Still it sounds like they expect openAI to extend full parity of features to a language that has only 7m speakers and appears "much less often online."
But I hope they do, for these people's benefit.
I was impressed with its performance in Irish but my expectations were much lower. Partly because in English it has given me nonsense code, and I think the poetry is terrible - only rhyming couplets (AABB rhyming).
