There are lots of advantages in general, especially around multithreaded code, and doubly so for anything with relatively simple data parallelism, where you can just use the rayon library. Another advantage is that there are Rust packages for Ruby interop -- the article ended up using ruru. There are similar libraries for Python interop -- I believe the most actively developed right now is PyO3. I'm sure people are sick of Rust evangelists on HN but it really is a wonderful language, and in certain cases it really does seem to empower people to do things they wouldn't have been able to do otherwise.
