The purpose of a universal intermediate language is to reduce the cost of 1-to-1 translation from an n^2 problem to a linear problem in n. An alternative approach is to brute force it by training an LLM on lots of code. "In the WMT25 competition, the model achieved first place in 30 out of the 31 language categories it participated in." https://github.com/Tencent-Hunyuan/Hunyuan-MT [That model translates natural languages, like Ukranian to Mongolian. I don't see how that's relevant to translating computer languages. In the former case, pretty close is useful, in the latter, pretty close is a program that doesn't work. -John]
