I’ve observed a connection between lovers of computer languages, and lovers of human languages.
If you are interested in coding or linguistics, are you interested in both or just one of of the two? If only one interests you, which one and why? If both interest you, do they seem related to one another?
Its hard for learning to be useless. Learning language of any kind, even if you dont use it as your primary, can open your mind to new ways of thinking about problems. Just having used the features or paradigms or what have you associated with the language can put new tools in your toolbox.
