I quite enjoyed this book, especially because of the history it touched upon. We zoom from the Library of Alexandria to Bell Labs in the U.S., from medieval scriptoriums to 20th C newspaper offices, from the birthplace of the typewriter to the office where the first email jumped from one computer to another. It‘s a rewarding journey, well researched. He could delete the entire last chapter & improve the book, in my opinion; the rest is great fun.
