Linus Torvalds has made his position on AI-assisted development in the Linux kernel official: it's staying, and dissent has the door.
The statement came in a post to the Linux kernel mailing list this week, prompted by debate over Sashiko, an agentic code review system designed to catch kernel bugs before humans do. Torvalds wrote that "Linux is not one of those anti-AI projects" and that anyone with objections could "do the open-source thing and fork it. Or just walk away." He added that he is "willing to absolutely put my foot down" on the matter — unusually blunt even by his standards.
Sashiko is the flashpoint but not the whole story. The tool's creators claim it independently catches 53.6 percent of bugs that human maintainers would later fix — a meaningful hit rate for a project as sprawling as the kernel. The catch: Sashiko also generates false positives at a rate its own maintainers estimate is "well within the 20% range," meaning roughly one in five reports wastes a maintainer's time. That tradeoff is exactly the kind of cost-benefit argument that divides working developers from AI skeptics.
Torvalds' stance matters because the Linux kernel is one of the most consequential open-source codebases on the planet, and his endorsement effectively sets a norm for how major projects handle AI contributions going forward. Other large open-source communities are watching — some have moved preemptively to ban AI-generated patches entirely.
A 20 percent false-positive rate would be disqualifying in most code review workflows, but Torvalds apparently thinks the tradeoff is worth making. Whether maintainers drowning in spurious bug reports will agree is a separate question.
