Memory safety is not some sort of binary thing which you either have or you don't. All memory safe environments are built on a foundation of unsafe code. For example, Java being memory safe assumes the JVM or JNI code doesn't have any memory safety bugs.
What Rust does is reduce the amount of code that's memory unsafe, that needs to be triply reviewed and audited. Reduction of the scope of high-scrutiny code is the single most leveraged thing that can be done to improve code quality in a large, long-running project. Why? Because it lets you do careful, time-consuming analysis on a small part of your codebase (the bits that are marked unsafe), then scale the analysis up to the rest of your code.
> These stories are mutually inconsistent. Either you have memory safety or you don't.
This is... what can I say. This is simply incorrect. It pains me to say this as a fan of your games but you really don't seem to have any idea what you're talking about.
