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.

You conveyed that? How?

Really, what neat little delineation is there between your little OS hack-on world and people using whatever language they want to make their software? There isn’t. Because people on a long-running project can have members who want to move code over or start modules in Rust or whatever language. As is happening in some places.

Beyond that though the projects that one is interested in would need to remain static and not include potentially new projects written in upcoming languages.

Against that backdrop we have you, moaning about lang X potentially infecting your OSS ecocsystem.
