The formal perfection of a language does seem to have a great deviance from the likelihood that it serves as a basis for important work. That is pretty simple to explain. Well designed languages have a learning curve. They require an initial investment in terms of learning — something that a lot of self styled hackers are not willing to put in. I am sure a ton of stuff is written as shell scripts. And there is also the matter of how long the language has existed.
