We never mention anything about superiority nor compare with other languages or programming models. This post is about making existing Rust CPU code work on the GPU.

I'm not a Rust user apart from an occasional toy program here and there, but you seem really triggered about a language that other people use. What's the issue?

I care because it means I can use this in a Rust program without a FFI barrier. Regrettably, we have built computing infrastructure as a society with many barriers; programming language is one.
