Ideas/Things about the Book "Deep Work" Cal Newport

I am currently reading the book "Deep Work" by Cal Newport and would like to hear the opinion of other people who have read this book.
In my opinion it is one of the most "real" books I have ever read that portrays exactly what is going on in society today, both in terms of mentality and economics.
It talks about the 3 big groups, "the highly qualified workers", "the superstars" and "the owners". What is your opinion about these groups and how they fit into our reality today.
