For the Linux kernel? Absolutely. Rust is way too unstable right now for such an important piece of software. Give it 20 years and a standard, then we can talk.
Based on what? The relevant folks and decision makers are already talking, so it doesn’t sound like they think there’s a need to wait 20 years to at least start the conversation.
Writing some optional, non-essential piece != rewriting a piece that will require taking rust as a dependency for the rest of time.
The kernel folks just did a lot of work to remove the strict dependency on GCC. To think any of the big players [Red Hat et al] want to turn around and make their shining star dependent on a language that's been 1.0 for less than 5 years is just not realistic.
