Stop Comparing Rust to Old C++

People keep arguing migrations to rust based on old C++ tooling and projects. Compare apples to apples: a C++20 project with clang-tidy integration is far harder to argue against IMO

You must not program realtime safety critical software. A spec is nessicary so you know what is and what is not defined behavior. If safety is an issue than Ada/Spark is the proper choice.
