I think learning Julia + git (CI is kind of thrown in, it’s more of a habit 
) is for someone who knows how to program already (in any language), and is somewhat computer-savvy (power user level, can install programs, interpret an error message, follow a tutorial).
I don’t think anyone would suggest that someone who is learning programming as something new start with all this. But for those people, I may not recommend Julia anyway — it is possible to learn as a first programming language, but a lot of the details just won’t make sense for a while.
