As is C++ which I compared it to, where there is even more boilerplate for similar tasks. I spent so much time working with C++ just integrating disparate build systems in languages like Make and CMake which just evaporates to nothing in Rust. And that's before I even get to writing my code.

I'm not saying there's no cost. I'm saying that in my experience (about 4 years into writing decently sized Rust projects now, 20+ years with C/C++) the cost is lower than C++. C++ is one of the worst offenders in this regard, as just about any other language is easier and faster to write software in, but also less capable for odd situations like embedded, so that's not a very high bar. The magical part is that Rust seems just as capable as C++ with a somewhat lower cost than C++. I find that cost with Rust often approaches languages like Python when I can just import a library and go. But Python doesn't let me dip down to the lower level when I need to, whereas C++ and Rust do. Of the languages which let me do that, Rust is faster for me to work in, no contest.

So it seems like we agree. Rust often approaches the productivity of other languages (and I'd say surpasses some), but doesn't hide the complexity from you when you need to deal with it.
