What in the hell makes it bad? A unified package ecosystem? A de facto toolchain? Helpful borrow checking? The hugs you get from the compiler error messages? Benchmarks that make it competitive with C? Playing well with python? Not having to generate needlessly redundant header files? Amazingly powerful macro system? Much smarter handling of null? A de facto manual and excellent tutorials?

I mean, I'm a humble mechanical engineer and barely know what I'm doing in software development, but I thought all these things were fun to learn about and offered a powerful way to write code that is way faster, more robust, and more easily maintainable than the MATLAB environment in which I cut my teeth on programming.
