I'm not sure Iran/Persian culture in particular is of importance in this phenomenon. To me, it seems it's just downstream effect of LLMs are only really able to operate internally in en-US. IMO, large language models are implementation of fundamentalist understanding of Sapir-Whorf hypothesis - Wikipedia[1] defines linguistic determinism as follows:

  "Linguistic determinism is the concept that language and its structures limit and determine human knowledge or thought, as well as thought processes such as categorization, memory, and perception."

That's basically an orbital level description of a multimodal LLM. No?
