> How did a language that's supposed to be so hard get popular to the point where people view its fans as pushing it aggressively?
I think Rust is especially popular with a demographic that was not previously exposed to lower level programming. Meaning younger programmers (because modern languages are higher level) and web centric programmers (because we're in a boom of web development).
This demographic had a hard time entering systems programming, because while fascinating, its exposure is lower (less jobs, less projects), and entry cost (learning C, or C++<11) is harder.
Rust made systems programming more accessible, and systems programming, just as anything related to how things work under the hood, is fascinating.
Now Rust is hard, as you noted, but not hard in the same sense than C is hard.
C is hard because low level stuff bites you immediately. You can't quite easily just use a random library in C if you don't understand your build system, linkage, etc. If you mess up in C, the compiler will not tell you either, you will have to debug your way out of it.
Rust is different, in the sense that its difficulty is limited to the compiler saying "nope". If you can get the compiler to say "yep", then you're 99.9% of the time safe. Now getting that compiler to say "yep" may take time, indeed, but all in all you most often can just get away with sprinkling unwraps, clones and Arcs all over the place until it works.
In that sense, I think Rusts popularity essentially lies in the fact that it is a way to do low level stuff with a barrier of entry limited to being stubborn in learning it.
Having learnt C in high school, and doing Z80 Assembly prior as a 12 year old kid, only with a bunch of books from the local library, it is kind of interesting to read about fear and hard regarding C.
Yes it does corrupt memory, there are some crashes, I usually bash C, nonetheless it seems we have too much "safety playground" regarding learning processes nowadays.
