Rust is not a toy. It's possible that your prejudice stops you from seeing Rust's benefits. It's also possible that you're working in a niche where Rust's advantage compared to C or C++ isn't as great as for most other areas of software development. And that's okay, Rust isn't quite there yet. For some very small niches, it might never be.

Frankly, even with those "decades of knowledge", C programs and libraries are still full of security vulnerabilities caused by C's limitations and memory handling. How many more decades will it take? How many more thousands of vulnerabilities?
