For existing code in the QA he said leave it be and it's better to fix.

For new code, he's recommending Rust and the advantage he talks about is that it makes the code more maintainable by people. And one thing that every AI coding talk I've seen agrees on is that what makes code more maintainable by people also helps AI and vice versa.

People and AI both have limited attention and memory. The less context necessary the easier it is to evaluate safety.

Another thing not in the summary he touches on is hardware safety. Not just software bugs but also compromised hardware which if your driver is memory safe can also prevent a buggy or adversarial piece of hardware since the hardware is effectively user input.

To balance out OP's selective quoting to avoid people strawman-ing his argument as a fanatic who can't balance risk:

"No, we don't want [rust] rewrites, so unless you're the maintainer and owner of that file, just do it for new stuff. Leave existing C code alone, and let's evolve forward after that."

Now, that doesn't mean he thinks Rust is magic. It's not. He cited one of the first Rust components merged into the kernel: QR code display logic used when the kernel crashes. "That logic was written in Rust. Famously, it had a memory bug. It was given a buffer and its size, and the rest of the st code never checked the buffer size... Could scribble all over memory..."
