Torvalds is mostly merging code in the kernel, not writing modules. He claims he's a manager now: https://www.zdnet.com/article/open-source-summit-linus-torva...
But he's very pro-ai, though, and is vibe closing other projects like https://www.phoronix.com/news/Linus-Torvalds-Vide-Coding
Linux is definitely going to speed up as it starts to get vibe coded. In a few years, I bet that it's all going to be built with agentic loops, and nobody will be looking at the code at all.
Imagine calling Linus a vibe coder... go look up the definition and then re-evaluate your statement.
