> GCC

Isn't needed if we rewriting anything in Rust anyway.

> GNOME, KDE

They aren't that huge. Huge is the overall codebase of applications using them. It's relatively easy to create a native Rust GUI framework and rewrite applications needed such a framework one by one.

> Linux kernel

It's a good opportunity to rewrite it. Not only because modern languages like Rust are better than C, but because such a rewrite allows getting rid of old stuff present only for historical reasons.

> BSD variants

Aren't needed if we writing a new kernel from scratch.

> CUDA, OpenCL

Not a huge problem. There are dozens of GPU-related languages. Adding one more isn't that problematic.

> Vulkan, DirectX, Metal

They are language-agnostic (but still unsafe). One can create an implementation in something other than C.

The fallacy starts that Rust depends on GCC and LLVM, and someone will keep adding code to them.

Likewise with all the industry standards based on C and C++.

Looking forward to see how COSMIC ever manages to gain adoption beyond System 76 computers.
