To me, it looks like the five-and-ten problem is that the quotation is not the referent. It seems to me that a program reasoning about its utitlity function in the way explained in the article is like a person saying " ' "Snow is white." is true.' is a true statement." The word true cannot coherently have the same meaning in both locations within the sentence.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
