Linus Torvalds to critics of AI coding in Linux: “Fork it. Or just walk away.”
Linux creator Linus Torvalds has strongly defended the use of AI coding tools in Linux development, telling opponents they can fork the project or leave. His intervention matters because it signals that the kernel’s top maintainer sees AI as an acceptable tool when it offers technical value, despite growing divisions within open-source communities over AI-generated code.
The discussion centred on Sashiko, an AI-assisted kernel review system said to identify 53.6% of bugs later fixed by humans, but estimated to produce false reports within a roughly 20% range. Torvalds said contributors would not be forced to use such tools, but he would reject efforts to prevent others using them; he also argued that AI’s mistakes should be judged alongside human fallibility. Earlier research found AI users were initially 19% less productive, though researchers later suggested the tools may have improved by early 2026.
In short
- Torvalds backs AI tools in Linux development.
- Critics can fork Linux or leave.
- Sashiko finds bugs but produces false positives.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
AI tools can help maintainers find bugs in a large, complex codebase, and the reported detection rate suggests they may offer useful leads even when some reports prove false. Allowing contributors to choose such tools preserves technical experimentation, while judging their output against human fallibility recognises that review already involves mistakes and should focus on results.
The case against
A substantial false-report rate can burden reviewers with extra work and distract them from more reliable checks; the reported productivity research also cautions that these tools may slow contributors down. In a project where maintainers must protect code quality and trust, opponents can reasonably argue for stricter limits until the tools’ benefits are clearer, especially if AI use changes how code is reviewed or accepted.
Explained simply
Linux is the open-source kernel that powers countless devices globally, from data centre servers to mobile phones. Created by Linus Torvalds in the 1990s, it is now developed and maintained by a worldwide community of volunteers and paid developers. Because Linux underpins so much critical infrastructure, decisions about how it is developed matter far beyond the technical community.
Artificial intelligence tools that assist in writing and reviewing code are becoming increasingly common in software development. There is growing disagreement within open-source communities about whether AI-generated or AI-assisted code should be accepted into major projects. The concern is partly technical—whether these tools produce reliable, secure code—and partly philosophical, about the role of human judgment in creating software everyone depends on.
Linus Torvalds holds significant authority over what changes are accepted into the Linux kernel, making his views on development practices consequential across the industry. The debate over AI tools in Linux development exemplifies a larger question facing open-source communities worldwide. How major projects decide to handle AI-assisted development will likely influence approaches adopted by other software projects.
