Logically Linux development ought to be collaborative
Many of the arguments here like this one which seem to make technical points are logically flawed this one for example "begs the question" the premise (e.g. Linus not accepting C++ is a similar incident and equally flawed decision since memory safety is desirable and a move away from C to a so called memory safe language will help) assumes the conclusion (e.g. Linux should use Rust now).

The major open source communities seemed to be on a path to more respectful collaboration Linus Torvalds efforts to moderate his tone perhaps being one of the best examples of this. It is reprehensible that as Microsoft Oracle IBM et al have begun to contribute to open source more one of the major impacts has been a return to flame wars and identity politics.
On the Rust for Linux front the way Rust and other "memory safe" languages are deemed to be "memory safe" depends on libraries maintained by humans. Just like the security and utility of the linux kernel is maintained by humans known as maintainers. It is not clear to me that outsourcing this security to another project that whilst by introducing opportunities for standardization and re use may reduce the diversity of error cases and vulnerabilities will also reduce the number of developers actively working on problems of memory safety and fully conversant in these considerations would in the long term actually improve the security of projects which move to memory safe languages solely for this purpose.
The idea that C cannot be developed securely as there "are not enough young developers", the language lacks the capabilities, not using the RUST or C++ apprach and outsourcing this to an ever smaller community is not sustainable seems flawed to me and invites the question well why is the security record of Linux distributions compared to Windows and other operating systems which have of late fully embraced this approach comparable if not better than these rivals?

I do not claim to know the right answer but allowing contributors to collaborate respectfully on proposals and the open source community projects to move forward without inviting lay people, anonymous accounts run by community members, vested interests, and trolls who want to see the world burn to weigh in on social media and attack volunteers who are often unpaid seems like a better approach to a viable solution for my money.
