For me it's more "I've used emacs for everything for decades, and coincidentally that means I use it professionally too". (At my current company we acknowledge that it's a generational thing and encourage new hires to pick an editor and obsess over it, since they'll be "living in it" and being able to manipulate things in your editor without thinking about the editor is a huge productivity hack (up there with learning to type), but we don't actually push them towards a specific tool.) ("Languages" (in the "things you edit" sense, rather than the Turing or LLM sense) involved include python, C++, json, yaml, cmake, and arbitrary unix config files.)
