Indonesia has over 700 regional languages, maybe trying to incorporate the smaller languages will finally cause GPT5 to explode.
As to the "23 million" speakers of Bahasa Indonesia - not sure whether this is quoting Altmann, but no, most Indonesians speak Indonesian, many of them bilingual with their regional language. See here: https://indonesian-online.com/indonesian-native-speakers/
And finally ... having recently spent 2 merry hours in the queue for immigration at Ngurah Rai airport, I wish Mr Altman a happy time with his golden visa <- sarcasm, in case you were wondering.
