I don't know why this reads so skeptical:

"The team has been setting the groundwork for new components/drivers to be written in Rust but as these are developed, we're running into some roadblocks," he told us. "[Linux creator Linus] Torvalds doesn't seem to care, or perhaps believes they are appropriate. Time will tell."

Some days ago what I read was this:

Switching to a more modern topic, the introduction of the Rust language into Linux, Torvalds is disappointed that its adoption isn't going faster. "I was expecting updates to be faster, but part of the problem is that old-time kernel developers are used to C and don't know Rust. They're not exactly excited about having to learn a new language that is, in some respects, very different. So there's been some pushback on Rust."
