Ungrateful 4 year old, he'll back before supper. If Ruby raised you well, I know python is a bit of a sloppy father though its heart is in the right place and he brings home the bacon, you'll know it's not just about the 5% code reduction. It's about abstracting away the inconsistencies of the language, revealing its inner elegance and power. CoffeeScript is not a cloak to hide JavaScript, it's the suit that makes you see and respect its power.
