What a case of assuming your conclusion. If Lisp is poetry, and poetry is beautiful-but-archaic-language-completely-divorced-from-ordinary-human-communication, well then obviously Lisp is for a tiny minority who like to speak Elizabethan; meanwhile the much larger population of practical people will simply prefer to get things done in vernacular.

It's nonsense, of course. If Lisp weren't good for getting things done, I for one wouldn't bother with it. But having assumed his conclusion in the first three words of the second paragraph, the author need offer no argument, and doesn't. In fact he doesn't even mention Lisp after that.
