"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" is not a good elevator pitch. Its a little bit of everything with no clear focus point.
So I'd say rust had better marketing.
Yet tons of people (like myself) who have preferred C to C++ still like Rust more. Categorization just isn’t that simple.
At least it's the reason I tried it once.
It was not a bad experience.
However i do wonder how big the market is for "python, but faster and multicore". I suspect it is smaller than "c but safe".
With Python I can just search "python <thing>" and find popular, well-maintained, libraries to do <thing>. I can't do that with Nim. Most of the stuff I find seems to be 5-9 years old and have no updates since.
Though I'm not really sure how often that happens these days unless you're trying to write code that's using an old protocol that's fallen out of favor, like IRC, FTP, or Gopher.
The problem is that CPython was never built with efficiency in mind and now it's hard to add it.
Not to mention, everyone aims for those traits. It is not unique enough.
