I don’t know. After writing rust for a while, and slowly putting programs together, I tried Go and I feel so relived I can just write what I want in 10 seconds instead of messing with lifetimes, borrow checker and other stuff I actually don’t care about at all.
A more experienced colleague said that yes that is true, but Go can’t guarantee your code is correct, so you will spend time fixing your code also in Go. Probably true.
That’s pretty cool. I’m not advanced enough to really understand all the ways rust is better but I read nothing but good things about it. It seems pretty universally loved.
Basically modern language with modern tooling. It’s what C++ would look like if it had been designed today. The big thing though is the abstraction of ownership and lifetimes which took C++ ideas of scopes, smart pointers, and destructors and polished them into something much more powerful. Simply put it’s possible to design APIs in Rust that are literally impossible to express in any other language, and that’s a big deal.
Added on top of that is a modern dependency management system that is severely needed in languages like C and C++, and a very powerful meta programming system that enables compile time code generation and feature selection that’s much safer and powerful than C and C++ fairly primitive pre-processor (although C++ STL does come close).

This sort of violates what I’ve always heard about computer science. I’ve always heard logic is logic.
Hmm, yes and no. You can express a program that does anything in any language, but API design is as much about what can’t be expressed (with that API) as what can. A well designed API lets you do the things that are desirable while making it impossible to do things that aren’t. You can of course bypass APIs to do anything the language allows, even in Rust if you break out the unsafe blocks and functions there’s pretty much nothing you can’t bypass with enough effort, but you very much have to set out to not use the API to do that.
I think your quantifier of “any other language” is the issue. There are certainly languages with far more powerful type systems than Rust, such as Coq or Lean.
