The debate around the integration of Rust in the core Linux is far from peaceful. Faced with a community of developers historically anchored in the language C, Rust proponents make arguments for security and robustness. However, this initiative provokes mixed reactions from those who reject this change, illustrating a technological divide that seems increasingly difficult to overcome.
A difference of opinion
Linux kernel developers express concerns about the inclusion of Rust, seeing it as an added complication. Some maintainers even argue that adding multilingualisms in a project as large as Linux could harm the maintainability. This resistance is based on several elements:
- A notion of purity of C-based code.
- Skills largely developed around traditional language.
- The fear that adding Rust will create interference in future development.
The words of a manager
In this context, a Linux kernel maintainer called the Rust integration a “cancer”. This provocative metaphor demonstrates a strong disapproval of a mixture that he considers unwise. This view is shared by many of his colleagues who fear a dilution of the standards already established. This type of reaction symbolizes:
- The concern of veterans of C development in the face of an emerging technology.
- A feeling of defending what has been acquired against the unknown.
The advantages of Rust
Despite the opposition, supporters of Rust argue many advantages linked to its use in the Linux kernel:
- Security data thanks to better memory management.
- Robustness applications, reducing the risk of conflicts.
- Modernity current projects that can benefit from an upgrade.

A question about the future
The path to coexistence between Rust and C within the Linux kernel raises many questions. What will be the real impact on the maintainability of the code? How will new generations of developers react to a language as old as C? The transition will not be easy, but it is seen as necessary to evolve in response to modern security challenges.
