Quoting Linus Torvalds

Simon Willison · Aug 22, 2026 · Engineering Insights

Linus Torvalds used AI as a debug assistant on Linux kernel code, crediting it with commit message authorship.

“And this was a debug session from hell, enormously helped by an AI doing much of the grunt-work.”

Linus Torvalds publicly credited an AI assistant with helping debug a complex Linux kernel graphics driver issue, even allowing it to write the commit message. He noted the AI repeatedly declared the problem unsolvable but continued generating debug code when pushed, revealing both the utility and the limits of current AI coding tools. An endorsement of AI-assisted programming from one of software's most skeptical and influential figures is a notable cultural signal for the industry.
