From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Switching everything from C to Rust because it has better memory safety is more akin to changing languages from English to Esperanto because it has gender neutral pronouns and other cool features. Maybe it's a good idea, but it's understandable that some people are reluctant.
I understand that position. I also understand how the words and phrases that the C community has used to communicate with the Rust community seems to be completely dismissive, not just reluctant.
I quoted what I did explicitly because of how a statement like that comes off to the person it's aimed at. It doesn't make them feel like they're on an even footing working on the same project with the overall goal of it becoming better.
I mean... not at all? Memory safety is huge for cybersecurity, buffer overflows and the like are common attack surfaces. C requires you to have deep knowledge of safe memory management practices and even then you can end up with memory issues. Rust was developed to avoid such issues entirely. I understand the reluctance but it feels to me like arguing "we should just stick with COBOL because it works."
Gender neutral pronouns are pretty huge too. Sure you can do them in English without too many problems usually, just as it's also possible to code safely in C. It requires everyone to change their old habits, but it's much less of a change than is involved in adopting a whole new language.
Anyway, I do like Rust better personally.
I would still say that getting people to the point where they can write safe C code every time is harder than learning Rust, as it’s equivalent to being able to write rust code that compiles without any safety issues (compiler errors) every single time, which is very difficult to do.
