So it's not as damning as you seem to suggest.
But yes, rust is definitely pretty cool, and I'm annoyed that I finally "understand" the language on my nth attempt at learning it, and still haven't found a good use case for it.
We out here like, “I’ve been getting really into this new language, 12,447. I think it might finally be the thing to replace 3 for me.”
C was just intended to be third in that very specific lineage, and I wouldn't be surprised to find it wasn't really third and just making the claim with its name.
Not to mention several more advanced than C, Go, or even Rust... (Lisp, for one, Smalltalk for another)
I encourage people to try writing run of the mill blocking code with Rust instead of diving immediately into futures and thread pools and streams just as if you were writing run of the mill Python.
It's generally 1:1 equivalent to the code I would've written in another language.
It's a general purpose programming language where most of the learning curve is in more advanced topics like concurrency, streams, and how to multiplex over thread pools. You can ignore them at the start, just like you can in Python.
