I think he was confused and what he meant to write is this: "To build this driver, more Linux source files have been read than any human except Linus Torvalds and a select few have ever read".
I'm not discussing whether or not license do still apply after code has been used to train a LLM and then the LLM spouts back another implementation (although it's been shown if I'm not mistaken a LLM reproduced Harry Potter verbatim and I take it that if it's word-for-word, license to apply after all)...
But saying "No Linux source file were ever read" when LLMs have been trained with every Linux source file ever, going back to when Linux wasn't even using Git yet, is quite something.
That's literally how LLMs are trained: by being fed a shitload of data.
P.S: I'm no hater btw: I pay Anthropic and use Claude Code daily (today we're writing some elisp code that calls tree-sitter).
