I think it's important to show students how to think about languages as a set of tools. OP's post stabs at this quite well, with the "Languages are less important than you think" section, and as someone who has already jumped across 5 or 6 languages over the course of his just over 10 year pro career this definitely rings true. I think it's fine to bag on languages like Racket, but a good engineer should be able to hop across any language and at least be able to read and understand what they're doing.
