At first, I was taken aback at how thick the book was and turns out it was very long to read with a very advanced choice of words for every paragraph used in the book. What made these innovators stand out and succeed more than other, how did they keep up with the evolution of technologies from the 1900s until now, so although the book was very difficult to understand I was studying a lot of the life of very significant people and get into the history of how they started and their vision of the future during their time. Other than this, I love the writer's style of writing. The way Walter Isaacson managed to complete each narrative with a ridiculous and entertaining backstory is chef's kiss.
