The existence of oh-my-zsh has always implied to me a common pronunciation that rhymes with "gosh", which is really the only way their play on words works.
I took a couple of compiler courses in university, and I think for the most part it made me a better programmer, mainly because it enforced understanding of how specific programming concepts and constructs are generally implemented. That, and a more intense look at the "heap of abstractions" you're generally working with when you write a higher-level language.
I've always advocated that, if you want to really understand the tools you are using, you need to understand at least one level below the "surface abstraction" that you are working if. Even better if you can understand two or three levels down.
There's a great talk from game developer Jonathan Blow [1] that describes how knowledge is lost "generationally" due to our lack of understanding of the black boxes we build things on top of. Not sure I 100% agree with his thoughts, but it's an interesting take.
