Seabrook's original article (in this book) is very helpful for balancing out the artistic license taken in the movie script - giving inventors the stark truth about what happens in the life of such a cognitive applicative person, with far less of the conjured-romance of a Hollywood script.
For inventors, this is a wonderful modern day accounting of many creative people. We read the notables such as Franklin, Edison, Einstein, and Tesla, plus the lesser-knowns like Hammond, and Crosley, but Seabrook brings home the modern day reality that inventing and creativity are hard work, with varying rewards - not always joyful, but pleasing to some.
Many people wrongly think inventing is the same as they imagine winning the lottery. The odds for the lottery are steep, and if you do win, total personal imploding destruction within two years is fairly guaranteed (1 to 2 out of 10 survive). Seabrook chronicles the heartbreak and the elation of being inventive, but it becomes clear, when an inventor "hits" on a "big one," it HAS taken lots of hard work, long hours, and it isn't because of luck that the invention made it.
The book itself will likely be catalyst to many a future flash, for inventive-minded people. For others, it will merely be tales of icons and legends. Nonetheless, Seabrook is to be applauded for his continued fascination and chronicle efforts. He's a wonderful wordsmith and this is a pinnacle compilation work for him. Thanks for producing the effort John.
