Rust excels in writing fast and efficient libraries that are portable and caller-agnostic. Java, C# and Go all have GC-endowed runtimes, so they might fare not as well on that field. On the other hand, GC allows for faster and easier programming without the need to reason about lifetimes, like you would have to do in non-GC-languages like C and Rust. Java, Go and C# are fast enough to do a lot better than scripting languages, plus they are statically typed and safe. I think that what Rust provides for user of those languages, has more limited scope: mainly squeezing the last drops of perf, and especially doing some realtime programming. Edit: One additional pro of Rust is that it managed resources like files and sockets very robustly with its type system, which may help prevent bugs. That's a thing CG won't do for you.
