Additionally, even if an LLM-created Rust port of a C++ library was bug-free, an LLM cannot recreate the community that has evolved around the library.

Take PROJ for example, which is the de-facto coordinate systems library in the geospatial world, mostly written in C++. The processes and trust built up with external organisations like national mapping agencies is irreplaceable.

That hasn't stopped people trying to vibe-clone PROJ in Rust though.
