Linus Torvalds backs AI coding tools in Linux kernel, tells critics to fork off
The Linux creator's endorsement of AI-assisted development carries major implications for the blockchain infrastructure that runs on his operating system.
Linus Torvalds, the creator and top-level maintainer of the Linux kernel, has drawn a line in the sand. In a lengthy post on the Linux kernel mailing list dated July 15, 2026, he declared that AI-powered coding tools are welcome in Linux development, and anyone who disagrees can, well, fork it.
“Linux is not one of those anti-AI projects, and if somebody has issues with that, they can do the open-source thing and fork it. Or just walk away,” Torvalds wrote.
From skeptic to supporter
Back in October 2024, Torvalds called 90% of AI messaging “marketing hype.” By mid-2026, the man is willing to, in his words, “absolutely put my foot down” in support of AI tools for kernel development.
The catalyst appears to be Sashiko, an AI code-review system developed by Google engineers that became open-source in March 2026. Sashiko uses large language model agents for automated patch review, and has reportedly identified around 53% of bugs in tested code sets.
Torvalds isn’t blind to the downsides, though. In May 2026, he noted that AI-generated bug reports had made the security mailing list “almost entirely unmanageable.” He also acknowledged that AI integration creates additional work for maintainers, and that LLM outputs can be inaccurate. But his argument boils down to something simple: ideological bans on useful technology are counterproductive.
Why crypto should care about kernel politics
Linux is the operating system running underneath the vast majority of blockchain nodes, validators, mining operations, and DeFi infrastructure. Ethereum nodes, Bitcoin Core, Solana validators: they all run on Linux. If Sashiko can catch 53% of bugs in tested code, that’s a meaningful reduction in the attack surface for any system running on Linux, blockchain nodes included.
The broader AI-in-development trend
His earlier experience with AI tools, including using Google Antigravity for his AudioNoise project in early 2026, appears to have given him firsthand perspective on where these tools add value. The progression from calling AI “marketing hype” to actively defending its integration is notable precisely because Torvalds is famously hard to impress.
