Rust feels impossible to use until you "get" it. It eventually changes from fighting the borrow checker to a disbelief how you used to write programs without the assurances it gives.

And once you get past fighting the borrow checker it's a very productive language, with the standard containers and iterators you can get a lot done with high level code that looks more like Python than C.

I agree but it's not different than C with a decent library of data structures. And even when you become more borrow checker aware and able to anticipate most of the issues, still there are cases where the solution is either non obvious or requires doing things in indirect ways compared to C or C++.

The quality difference between generics and proc macros vs the hoops C jumps through instead is pretty significant. The way you solve this in C is also unobvious, but doesn't seem like it when you have a lot of C experience.

I've been programming in C for 20 years, and didn't realize how much of using it productively wasn't a skilful craft, but busywork that doesn't need to exist.

This may sound harsh, but sensitivity to order definition, and the fragility of headers combined with a global namespace is just a waste of time. These aren't problems worth caring about.

Every function having its own idea of error handling is also nuts. Having to be diligent about error checking and cleanup is not a point of pride, but a compiler deficiency.

Maintenance of build scripts is not only an unnecessary effort, but it makes everything downstream of them worse. I can literally not have build scripts at all, and be able to work on projects bigger than ever. I can open a large project, with an outrageous number of dependencies, and have it build on the first try, integrate with IDEs, generate API docs, run unit tests out of the box. Usually works on Windows too, because the POSIX vs Windows schism can be fixed with a good standard library and cross-platform dependency management.

Multi-threading can be the default standard for every function (automatically verified through the entire call graph including 3rd party code), and not an adventurous novelty.
