This was just an interesting supporting point in his larger argument of reforming American education. I would not remove foreign language requirements entirely but I support giving students a choice in what they learn.
Foreign language is a skill that enables you to communicate with the world around you and that world around you is now becoming increasingly computer-centric. I can see his argument. I never had a chance to learn CS in school as I was too busy filling in all kinds of requirements for my major. All kinds of things I rarely use today, it would hav e been nice to have the option to dabble in JS as a "requirement" in college!
However I just reloaded the page and it's showing a different code snippet and says 1 of 3 completed.
