The choice of language 15 years ago has nothing to do with the languages that could be in use today on the same project.
Rust has `unsafe` all over the place; it's no more safe if you use that keyword to do the same things that are done in C++.
Get more compiler people on Go and it will be even faster than it is now (really fast), and Go is written in Go so there's no reliance on C++, unlike Rust.
