1% of code in some obscure module that's barely used being written in Rust does not give one claim to those things being written in Rust. Even Firefox is only 10% Rust despite the language being designed by Mozilla, and they abandoned their project to write a new browser engine in Rust.

It's not "some obscure module" that is written in Rust. Just some examples I know of:

- Chrome currently uses https://github.com/googlefonts/fontations to implement its font handling, and text is the main thing on most web pages.

- Windows' DirectWriteCore for font handling is also now written in Rust.

- Firefox's whole CSS engine and GPU 2D rendering engine are written in Rust.

What is your point?

I pointed to a jetbrains study, and then there's a stackoverflow survey[1] showing C neck and neck with PHP at 11th place among professional developers.

We all know there's lots of important C code out there. I don't see anyone going "RIIR!!!" in this thread.

But obviously yes, the 11th place language will have MANY programmers working on it. Not as many as JS by far. But many. In that survey Go is just after PHP. There are also many many Go programmers.

We are not yet at risk of running out of C programmers, like the Cobol situation. Nor do I want us to.[2]

But what point are you trying to make by so strongly defending C and the comment "grownups with important jobs write C"?

The point I am trying to make is that C is a production language and Rust is not a production language, so the original comment is pretty much correct if you take adults with jobs to mean writing software used in production. People use JS, your JS engine is written in C++, running in a browser written in C++, running on an OS written in C/++. Whatever higher-level language you use, it's powered by C/++. Your game engines are written in C/++. Your fucking car is written in C. It's not even an argument about what is better or what people should use or anything like that. It's just acknowledging reality. You're talking about how "writing new C in 2026 is misconduct" like it's a relic of a bygone era when in actuality the world around you is a world written entirely in C with, rounded to a whole percent, literally 0% of the software anyone uses being written in Rust.

		> Rust is not a production language Your argument was that the only Rust projects there are are little developer tools, so Rust isn't a production language. When pointed out there are large projects that every day users rely on that use Rust, and not just in corners of the codebase, code that's exercised by approximately all users, you insist it's still not production?

		> Rust is not a production language because so much legacy code You must not exist, because, rounded to a whole percent, literally 0% of the lives of people in the world are directly affected by you personally
