The problem is that for complex enough projects, the architectural redesign is considerably more demanding than a "remaining 20%". I can imagine it also being quite irritanting, due to shortcuts one may take in C taking advantage of implicit application logic (independently of them being warranted or not), that can't be directly translated due to the Rust strictness.

I wonder if the brainiacs at OpenAI could train a neural net on human-written C -> Rust translations.
