The Innovators: How a Group of Hackers, Geniuses, and Geeks Created the Digital Revolution

Author: Walter Isaacson



If you live in Silicon Valley you must be curious about how all of the big technology companies got their first start. Walter does a phenomenal job in chronicling these events and putting them in a narrative that is a joy to read. He has interviewed a large number of people who were around when history was being made and you get the feeling like you were watching some of these iconic inventions grow up into adulthood.

The book opens with Ada Lovelace and the interesting times she lived in.  I do confess that the subsequent chapters on the early computing inventions like the  ENIAC, Atanasoff’s machine, etc. were not too interesting to me and I almost abandoned the book.  But Isaacson pulled me right back in with the story of Shockley in Bell Labs, and his inability to collaborate with the other inventors of the transistor.  Once they moved to Silicon Valley, I felt like I was reading the history of my neighborhood and could not put the book down.


Apart from just re-telling history, Walter looks for a pattern in all these stories and draws some broad conclusions from them.  He highlights the importance of coupling people who have bold visions, with partners who can execute. This quote sums it up well “vision without execution is just hallucination”.  Another key insight is the big role that collaboration plays in all of the significant innovations. Visionaries like Shockley who were unable to collaborate effectively did not have as much success as others.  Similarly collaborative groups that lack visionaries (like Bell Labs after the departure of some of the visionaries) don’t innovate either. Another clear observation from the stories in this book is how great leadership teams are built by folks with complementary styles.


Anyone who is working for a technology startup or contemplating joining one will find this book inspirational. If you get past the first few chapters you will not be disappointed.

The organized mind: Thinking straight in the age of information overload

Author: Daniel J. Levitin


The title of this book is an overload in itself, but the premise is solid. We are faced with too many choices today and these choices make us less happy, not more. And the trend is getting worse.  Daniel makes his point by highlighting how the average grocery store now has over 40,000 unique products as opposed to less than 10,000 in 1975.  Most of our needs revolve around 150 products and so we spend a huge amount of cognitive effort ignoring the thousands of items in the grocery store.

Decisions like this are lurking at every corner of our lives. The online shopping marketplace has made it infinitely worse. I recall, going through the entire catalog (tens of thousands) of light fixtures in several online stores when I was remodeling my house a few years ago.  While driving, I often feel the need to consider alternate routes and optimize for traffic. Many people I know, watch a show on TV while checking their mobile phones for updates on Facebook, Twitter, Email, etc. Daniel underscores the point that all this context-switching consumes energy and prevents us from making good decisions. 

The book starts out with lots of promise, but Daniel strays in his thoughts. Halfway through the book, Daniel decides to focus on Bayesian statistics and goes off into a detailed description of how to calculate the odds that your test was a false positive. He then veers off into leadership and the US Army’s Mission Command manual. While most of the information resonated well with my view of cognitive behaviors, the book meandered about and made for a rather slow read.
