In a nutshell he says that Linux is a technology project, where technology comes first. If LLMs help to improve the technology then it's fair game. If not, then of course not.
He also says something about Linux not being a place for 'social warriors', which is kind of ironic, given that Linux is basically a big 'fuck you' against corporations and closed source, i.e., a scoial statement. Given how much beef he famously had with Nvidia, this is somewhat unexpected.
But I interpret it as coming from a place of seeing LLMs really just as a new tool and nothing more. In an interview a couple of years back, Linus also said pretty much that. He grew up with basic tools, had to create new software tools to make him more productive and improve the quality of his work. He saw LLMs just as another tool that can aid in development. I suppose this hasn't changed.
Given, that most people usually don't program in assembler anymore, but use high level programming languages like C++, which simplifies the process of coding enormously, or even scripting languages like Python, which present another level of abstraction and simplification, LLMs do appear somewhat like a next step in this evolution.
Issue is, you have deterministic and formal guarantees in programming languages, whereas LLMs do not. This is by far not the only issue of course, as others in this thread have also noted.
I wonder whether he uses LLMs in his daily work. Might change his perspective a bit.
