It is good to know multiple languages, but I think at some point you are only marginally making your job easier by learning yet another. The article, at least as I read it, speaks to learning something new that makes solving a problem, that was previously out of touch, significantly easier. Maybe a different programming analogy would be that you know C++, and then you learn some electronics and realize that you can now build a small wristwatch computer using a basic microcontroller – something that would have been impossible with the full-fledged PCs you are used to programming on.
