Yes but we're talking about today. And C's smallness/simplicity means that bootstrapping on new architectures is straightforward. Meanwhile Rust needs 64bit, etc. just to build. Rust's early embrace of compile-time complexity (ZCA) means this will always be a fundamental problem for the language. In fact it's getting worse over time.
