If so, the title of the article is meaningless clickbait. From reading the article it seems to me the author takes the phrase at face value as they imagine skim reading a third of Middlemarch in a day. I'm surprised they describe different modes of reading as a skill future people will have, since afaik it's normal for most people to approach different types of texts at different speeds and paying attention in different ways. I can skim quickly over comments and articles just building an understanding of the context and basic information and conclusions people are using, while I will read a scientific article anywhere between ½ and 3 pages per hour if I'm actually trying to understand a difficult concept.
