As I think I conveyed in my original post, I am not against anyone using whatever language they want to make their software. If a "genius" Rust program 'solved' cancer I would be exceptionally impressed by the PROGRAMMER's work, the language they used would not make a difference. Although I would be more excited to get the source code for the program if it was in a language I already knew and used routinely. My objection is to Rust being imported into software that I already use and is not currently written in Rust, and that is a very different thing.
