Do you mean Digital Minimalism? Cal Newport is the author of both Deep Work and Digital Minimalism but the latter book is the one that deals with the topic of the article.
I think Deep Work is highly related to the discussion of distractions and superficial "candy like" experiences. Pretty tough to do deep work (and conversely, easy to do shallow work) when you're assailed with notifications, constantly responding to texts, etc.
Deep Work's first maybe 3 chapters are all you need. Cal Newport is a master of writing some good blog posts on a topic, and then with padding them with 250 pages of boring drivel, and selling it as a book.
