For me the main selling point is that it allows me to do code with performance constraints without having to resort to a programming language without modern package management, modern documentation or a modern ecosystem. I would have jumped at any chance to do modern programming that way, and dodge C and C++. It is a double blessing that besides satisfying these rather basic constraints, it's actually a great programming language as well, improving safety and reliability, having a concise but expressive syntax, a powerful type system, even a novel solution for enforcing some safety in shared memory situations.
