The dotfile example pertinent, I can't be arsed to remember the syntax for every little thing that I don't interact with on a daily basis. Bash scripts, build tool chains, infrastructure code, all that tertiary stuff. While it isn't a huge number, the amount of time saved not having to google and relearn something every time I want to make a change adds up over time.

Of course this is undone by all the AI slop my boss passes by us now.
