I don't think "no people" should be seen as a hard rule. The Hopper paintings mentioned in the article, for instance, usually have a few people in them, and yet he's clearly aiming for the same thing as modern liminal spaces pictures and achieving it. Hopper paintings have only become more unsettling with time, because they feel so modern, like that was yesterday, when you know that objectively it was over 100 years ago.
