Don't forget "chic" languages like Rust have the whole C ecosystem at their disposal. Having done Java for many years and recently also done Rust, I'm not very convinced one ecosystem is richer than the other, when we talk about high performance computing. I've already hit a few things that are present in Rust I wished to have in Java. Generally I find the multithreading/concurrency libraries available in Rust very good.
