Nothing in particular other than knowledge that I can use across domains. I don't want to know how to write an interpreter per se, but I want to understand the steps from text to machine code.

I think it has already yielded benefits in my better understanding of environments and lexical scoping, grammars + LALR. It has just given me different conceptual tools that I can use to learn new concepts.

A concrete example was that I was playing around with a recursive prompt with ChatGPT the other day trying to figure out if I could get it to write a more specific version of a prompt I had given it and sort of bootstrap its way to a very specialized "train-of-thought". I was thinking about grammars and how recursive prompting is sort of like a meta-grammar. It's just a new way of thinking about things.
