Ask HN: Why did Nim not catch on like Rust did?

I skimmed through Nim website and some code snippets, and see very exciting features such as macro support, pythonic syntax, transpiles to C/C++/JavaScript, no VM, systems programming language, suitable for hard real-time systems etc. So why has it not caught on as wild fire like Rust?

Also, what is its FFI story? How easy it is to interop with C++ and JavaScript?
