> Rust is probably not even in the first hundred 'new secure languages that the kernel should be re-written in to solve all the evils of the world'
I never claimed that any language will solve all evils of the world, or that the kernel should be rewritten. But a programming language *can* solve silly things like buffer overflows (well, most of them) or format string vulnerabilities.
And let's not mention the fact that you didn't name even *one* argument why Rust wouldn't be a viable competitor. Especially when considering that I was talking about Rust 1.0 that isn't even released yet...

> If you think that writing a kernel in a different language is the right thing to do, go write it, and if you are correct and it is superior, you will displace Linux
So you're essentially saying that the success of a kernel is determined solely by the programming language it's implemented in? Because otherwise your point doesn't make any sense at all.

> Linus has said many times that he expects that eventually there will be some other kernel written that will replace Linux.
I don't think Linus is right about that. Linux is "too big to fail" by now, it's not going to be replaced. The best that one could hope for is an incremental solution to the C problem by allowing, say, some new drivers for non-critical hardware to be written in another language, and then gradually expand from there.

No it't the exact arguement you make in the next paragraph, its too big to rewrite.

He wrote this:

The only ambiguity here is what "it" refers to. It could be either the newly written kernel or the Rust programming language. However, with the phrase "if you are correct" he clearly refers to some statement I made earlier, and I never said anything about some hypothetical new kernel, so he must be talking about the Rust language. So I'm sorry, but what he was saying just rubbish; he probably meant something else but it's hard to tell...

> The 1980s called they want there micro kernels back
The whole point of using a memory-safe language like Rust in the kernel is *not* having to bother with a Microkernel architecture.
