Learning more programming languages will make you a better programmer irregardless as it will expose you to different programming patterns, paradigms and the limitations/improvements that result from those. This is especially true for a popular language, no matter if the language is considered "good" or not. This allows you to understand the libraries/code you will encounter down the road. I would only discourage one from learning a programming language which is tied to a specific commercial product (most of those just die in the same niche and thus lack the practical utility).
