Linus Torvalds used Claude on the Linux kernel — and told everyone else to stop sending slop
“Linus Torvalds used AI to rewrite part of the Linux kernel — then told the rest of you to stop sending garbage.”
The Story
Torvalds used Anthropic’s Claude Code for an experimental kernel patch series that tripled certain read throughput in his tests. He says competent developers should use AI as a tool and the kernel no longer requires declaring AI assistance if the code is good. He draws a hard line against “drive-by” patches from people who don’t understand the code they submit. Maintainers are drowning in AI-found bugs plus low-quality AI patches.
Why It Matters
The high priest of open source just used the machine and then defined who is allowed to. Builder identity, craft, and the coming flood of slop.
