I have saved instructions for Gemini to translate queries into the local language then retranslate the output back to English, when asking about non-English speaking countries/cultures. It seems to work fairly well, but I think it's just due to the different content trained in that language; obviously there would be more in depth discussion of Indonesian cuisine in Indonesian. Whether the country is rich or democratic shouldn't really affect the output.

That's interesting! I manually do the same by prompting in the target language, since it drastically changes the results.

This has been true of web search since forever mind you. The wev has always been culturally delineated by language, and the English Web as I call it is not the only web.
