I think the idea is the other way around. It's not about inventing a new language, it's about taking a jargon that already exists, is used and understood by domain experts, and make it executable. Less regex/XML, more nouns and verbs from a very specific business context.
Granted, even with that perspective, it's still a stretch to say little languages are the future, but both the article linked here and the one it's replying to are from 2004, so, there's that.
