AI has enabled my team to essentially all become polyglots. It's really amazing to be able to jump between languages, using the best tools for the domain.
* JS/TS - FE
* Ruby on Rails - Most of our business logic
* Python - Doc and LLM specific code
* Misc. other languages - niche features that make the most sense in specific languages.

Previously, we'd spend a lot of time on dumb little things. Things that you probably take for granted in your primary language, but can become super frustrating in a new language.
