Because none of them are an improvement over a shell. Maybe if there were a better way to pronounce "open paren" and "make-vector" we could just yell scheme at the nearest computer. IMO you're never going to get anywhere trying to make shells speak natural language. Even if you crammed a person into the box there's just way too much you could ask to narrow it down without something formal. At the end of the day you'll have to have something that looks like sh or any other formal language.
