I'm not so sure. Natural languages are not very much like programming languages. When you speak a language fluently you're able to speak and understand without thinking about it. Children can be fluent with no formal training in grammar. Meanwhile, for me at least, programming is the opposite: I have to learn all the rules on a formal level and my mind can't wander while I'm programming at all. I think the benefits of knowing more natural languages are pretty clear: the ability to speak to and understand more people. Plus the art, entertainment, and other cultural productions you get access to.
