Why was this downvoted? It's not just another generic "rewrite it in Rust" comment. I was making a specific point that incremental rewrites of existing C++ code are very possible in Rust. And that process would not be that different from rewriting the code in a "safe" dialect of C++.

If it makes you feel better you can rename the Rust language to "C++2.0" but the rewrite process itself will be the same in both cases. You keep expanding the amount of safe code you have within the codebase over time, one module at a time.
