Python, Java, and JS are all implemented in C/++. C++ is an extension of C. Taken strictly, sure, not everyone is literally writing C. But C powers everything. It is still the systems language of the world, that is the foundation of all of our systems, including both embedded and phone/PC OSes. Then there's a bit of COBOL and Fortran for mainframes, Ada for military hardware, and a whole notta Rust anywhere.
Think about what Rust software people actually use. Codex CLI, uv, ripgrep, and what else? That's three pieces of software, all development tools for development nerds. Normal people aren't engaging with any of this stuff. Your metaphorical grandma has never used software written with Rust in her life.
