From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

In some of its characteristics, Rust is certainly a good language. The borrow checker, however, still haunts my restless dreams today.
The borrow checker is exactly what the kernel needs.
I'm a C/C++ dude but I heard it being called the "Karen compiler". It doesn't look that scary based on samples I've seen, but there's way more to it I am assuming.
I'm no Rust expert, but in my experience the borrow checker is a pain for a bit, then you start to get a sense of what works and what doesn't, and after a while it has taught you to write cleaner code.
"Karen compiler" is almost perfect, except unlike Karens, the compiler is delightfully helpful with the error messages it gives you (usually). It usually gives a straightforward error, an error code, and sometimes, an easy fix.
As someone that started with Rust, but just yesterday had to fix some C++ code, working with any other compiled language makes me shudder. I have nothing but respect for devs that have to wade through stuff like that.
To be fair, most of them aren't as nasty as C++. But Rust certainly gives you a sense of security you don't get with most other languages.
At least it has something to complain about, unlike Karens.
Ha, I'll steal that! "Karen compiler" - quite fitting, to be honest.
Oh, so the main reason why it's so good?
I'm not a software dev (I'm a SysEng), and have never touched Rust (I've looked at the Rust source code and it scares me haha), but I know a fair amount of Go, and even the Go compiler is a pain in the ass occasionally. I've "mother fucked" it so many times.
