Linus Torvalds, the creator of Linux, has made his position unmistakably clear: artificial intelligence is a welcome and permanent part of Linux kernel development. In a recent exchange on the Linux Kernel Mailing List (LKML), Torvalds directly addressed critics who want to ban AI-generated code from the kernel. His response was blunt: those who can't accept it should fork the project.

"I realize that some people really dislike AI, but this is an area where I'm willing to absolutely put my foot down as the top-level maintainer," Torvalds wrote. He added that if someone cannot support the use of AI in the kernel, they "can do the open-source thing and fork it."

Why Torvalds Supports AI

Torvalds compared AI to other tools used in software development. "AI is a tool, just like other tools we use. And it's clearly a useful one," he said. He acknowledged that just a year ago the utility of AI was questionable, but now it is no longer in doubt. This shift reflects the rapid improvement of large language models (LLMs) and their integration into various stages of the development pipeline.

Torvalds also addressed the quality of AI-generated contributions. While he admitted that AI can sometimes be a "painful tool," he argued that the solution is not to ignore it but to ensure that AI tools help maintainers rather than create more work. He insisted that the Linux kernel community makes decisions based on technical merit, not ideological opposition to new technologies.

Other Kernel Maintainers Weigh In

Torvalds is not alone in his stance. Greg Kroah-Hartman, the maintainer of the Linux stable kernel, previously noted that AI-generated security reports have improved dramatically. "Months ago, we were getting what we called 'AI slop' — obviously wrong or low-quality reports. But then the world switched. Now we have real reports," he said. AI is now producing valid and useful contributions to open-source projects.

Theodore "Ted" Ts'o, a senior Linux kernel maintainer, also weighed in. He questioned how projects like the Software Freedom Conservancy (SFC) expect maintainers to accommodate individuals who reject AI entirely. Ts'o argued that it is not obvious that maintainers must bend over backward to satisfy every objection. James Bottomley, another top developer, added that contributors do not get to approve the tools maintainers use. "The contributor doesn't get to approve the tools the maintainer uses to assess and apply patches. If there's AI in there, and the contributor is an AI luddite, then the patch doesn't get applied," Bottomley wrote.

Background: Torvalds and the Evolution of Linux

Linus Torvalds created Linux in 1991 while a student at the University of Helsinki. What began as a hobby project has grown into the most widely used operating system kernel in the world, powering everything from smartphones to supercomputers. Torvalds has always been known for his strong opinions and direct communication style. Over the years, he has fiercely debated issues ranging from coding style to the inclusion of new features. His stance on AI follows that tradition.

The Linux kernel is developed by a distributed community of thousands of contributors. The kernel development process emphasizes rigorous code review, testing, and long-term stability. In recent years, the community has adopted many new tools, including Rust for kernel modules and, now, AI-assisted programming. AI is used for tasks such as automated bug fixes, patch analysis, and even generating code suggestions.

The specific trigger for Torvalds' recent remarks was a discussion about the SFC's policy statement on AI. The SFC recommended that projects "support, not just tolerate, those who outright reject LLM-gen-AI systems." Ts'o and others found this impractical, leading to the heated exchange.

Technical Merit Over Ideology

Torvalds' core argument is that the Linux kernel community should judge contributions by their technical quality, not by how they were produced. He compared anti-AI sentiment to earlier resistance against compilers, debuggers, or version control systems. Each new tool was initially met with skepticism but eventually proved its worth.

"In the kernel community, we do open source because it results in better technology, not because of religious reasons. And so we make decisions primarily based on technical merit. Not fear of new tools," Torvalds concluded. This philosophy has guided Linux through decades of change, and AI is no exception.

The use of AI in software development has grown rapidly. Tools like GitHub Copilot, Claude, and GPT-based assistants are now common. In 2026, frontier models such as Anthropic's Claude Opus 4.8 have significantly improved code generation and debugging capabilities. Many open-source projects have embraced these tools to accelerate development and reduce manual effort.

Implications for the Open-Source Community

Torvalds' ruling effectively sets a precedent for the entire Linux ecosystem. Projects that depend on the kernel may follow suit. However, some projects, like the Zig language, have explicitly banned AI-generated code. Torvalds' response suggests that such bans will not be imposed on the Linux kernel. Instead, developers who disagree can maintain their own forks.

Forks are common in open-source software. The Linux kernel itself has many forks, including Android's kernel and numerous specialized variants. Forking allows groups to create versions that align with their own values or technical preferences. Torvalds' invitation to fork is both a political statement and a practical way to avoid endless debate.

The debate also highlights a generational divide. Younger developers are often more comfortable with AI tools, while older programmers may view them as a threat to craftsmanship. Torvalds, now in his mid-50s, has shown that he is willing to embrace change when it improves productivity.

What Comes Next

The Linux kernel community will continue to refine how AI contributions are handled. Maintainers are likely to develop guidelines for evaluating AI-generated patches, much as they already do for human-written ones. The focus will remain on ensuring quality, security, and maintainability. Torvalds has made it clear that AI is a tool that can enhance the development process, and as long as it produces technically sound results, it will be welcomed.

Torvalds also noted that the economic implications of AI remain an open question. But for the immediate future, the question of whether AI is useful has been answered affirmatively. The Linux kernel will move forward with AI as part of its toolkit.
