Linus Torvalds on AI, Vibe Coding, and the Future of Linux Kernel Development

Interview context

At the Linux Foundation Open Source Summit in Seoul, Linus Torvalds was interviewed by Verizon open‑source lead Dirk Hohndel. The discussion focused on artificial intelligence (AI) in software development, the emerging role of the Rust language in the Linux kernel, and the concept of “vibe coding”.

Vibe coding

Torvalds described “vibe coding” – a mood‑based, exploratory coding style – as potentially useful for research or prototyping, but warned that it is unsuitable for production‑level kernel work because it can introduce maintenance problems and jeopardize stability.

Rust in the Linux kernel

He confirmed that Rust is moving from an experimental feature to an essential component of the kernel. The transition is progressing more slowly than expected, but the language is expected to become a permanent part of the kernel code base.

AI’s impact on development and hardware

AI‑driven advances have accelerated Nvidia GPU and CUDA development, influencing hardware evolution.

Torvalds noted that AI‑generated data collection on kernel.org creates “security noise” – large volumes of low‑value data that can obscure real security signals.

He compared the AI‑related noise to issues faced by other projects (e.g., curl), stating it is less severe but still a concern.

AI as a tool, not a replacement

Torvalds likened AI to a compiler: it can boost productivity but does not replace programmers. He has not used AI for kernel development and believes the community is watching the technology closely.

Stability philosophy

Torvalds emphasized that stability means avoiding “exciting new features” that could crash millions of machines. He prefers incremental, well‑tested changes over rapid, experimental additions.

Community interaction

Torvalds remains open to feedback via email, acknowledging that he reads many messages but may not always reply.
