I think architecture and UX have more impact on the quality of the software you write for the end user than the details of a specific language. And when you're creating guitar training software, music and guitar playing knowledge has more impact on the quality of the software, than the details of a specific language.

When working with an LLM i care more about prompting it about software architecture, software UX, and the domain we're working on, than the details of the language it uses.
