How often do you had issues like that in the last 10 years of your work? Questionable if it's really cheaper for everyone. Other question, is there any really large Rust codebase out there thats older than 10 years? That had time to gather crust of tons of developers to compare with the appropriate C++ codebases? I don't think so.
