Rust supports careful management of memory at the expense of unsafety, at which point that particular area of the code offers no benefit over C/C++, let alone value in a rewrite. There is no type system for reinterpreting bits of memory.

And for the safe parts, the posts that I've read from people who have spent a non-trivial amount of effort with the language do not paint a clear picture either on whether there was really a benefit to the language overall.

So to say that "the world has moved on" in light of all of this is pure hubris.
