Wedson Almeida Filho is a Microsoft engineer who has been prolific in his contributions to the Rust for the Linux kernel code over the past several years. Wedson has worked on many Rust Linux kernel features and even did a experimental EXT2 file-system driver port to Rust. But he’s had enough and is now stepping away from the Rust for Linux efforts.
From Wedon’s post on the kernel mailing list:
I am retiring from the project. After almost 4 years, I find myself lacking the energy and enthusiasm I once had to respond to some of the nontechnical nonsense, so it’s best to leave it up to those who still have it in them.
…
I truly believe the future of kernels is with memory-safe languages. I am no visionary but if Linux doesn’t internalize this, I’m afraid some other kernel will do to it what it did to Unix.
Lastly, I’ll leave a small, 3min 30s, sample for context here: https://youtu.be/WiPp9YEBV0Q?t=1529 – and to reiterate, no one is trying force anyone else to learn Rust nor prevent refactorings of C code."
If anything, the constant coddling of a few aging individuals within the kernel and the protection of their comforts is why Linux has been so slow to adopt technologies and paradigms that developers are begging for.
Linus complains of dev burnout starving the kernel of contributors, but the processes and technologies driving kernel development are antiquated, and the very suggestion of change is either discarded or makes you the target of a public shaming by Linus himself.
I agree with your views. But I have to give praise to Linus for bringing Rust into the kernel.
