The Fear Index – Robert Harris
This is the second “non-historical fiction” book (at least that’s what I would call it) from one of my favorite authors, Robert Harris. The first, “The Ghost” was a good book overall, but lacked a lot of the punch, interest, and intrigue as most of Harris’ other works. This one, though, I found incredibly exciting, hard to put down, and I finished it in only 3 or 4 days.
In all honesty though, I wanted a bit more. I felt as though the ending of the book still had some unanswered questions, and I was forced to speculate on what actually happened, why it happened, and wasn’t 100% sure that my conclusions are what the author intended. Of course I must concede that this could have been the author’s intention. Regardless, it was a great read and a compelling thriller.
The story tells a tale of Alex Hoffman, and incredibly smart eccentric billionaire. His claim to fame? He’s figured out a way to predict the stock market’s algorithms to where, regardless of how the overall market performs, his complex machine-learning program always manages to win the day and make him and his investors billions. Most of the predictable behavior that this algorithm utilizes is its highly accurate understanding of “fear”. When people get scared, they make decisions to fight, flight, fret, or freeze and nowhere is this more apparent than when individuals are trying to control their portfolio.
Now, it isn’t as though Hoffman and his cronies are causing unnecessary panic throughout the globe in order to improve their portfolio, but one can’t help but pity these individuals that would utilized the worst of human behavior in order to make such a mammoth profit. As we get to know Hoffman, we basically don’t like the guy. Wealth turns people into social recluses, and although his jabs at the rest of society aren’t necessary filled with vitriol nor malice, we still get the opinion that he has the opinion that his billions of dollars means he basically can do whatever he wants and doesn’t have to deal with anything that doesn’t interest him. Especially people.
Now, this is only part of the story. The other part is that as the story begins, Hoffman is attacked in his well-guarded, insulated private estate. Who is after him? And more importantly, how could they penetrate such an insulated security system. This is what adds to the overall flavor to the story, and the main goal of Hoffman’s predicament isn’t necessarily how to keep his massive amounts of cash flowing inwards, but what is going on with his psyche? Why is this intruder trying to hurt him? What exactly has he done? And why do strange, unexplained occurrences seem to be happening around him that are increasing his paranoia?
As I mentioned, I’m not sure the story wrapped itself up as tightly as I would have liked. In many ways the underlying theme, though, seems to be that artificial-intelligence can be much more problematic and harmful than the benefits that it seems to provide. Yes, the technology can help us all to things better and become more learned, but if people really are mainly motivated by fear, it’s a bit of a sobering thought to see how all of this machine-learning can be used against us. I read this book in 2026 (it was written in 2011), and as I look at the world around me, it does seem to appear that the world is finally starting to see that these advances in technology might not necessarily be the panacea that many thought it would be, and it’s rather being looked at as a scary Pandora’s Box.
I’m sure there have been masses of books out there about this scary latter day development, and without reading any, I can’t really compare. However, this book was a very satisfying, yet somewhat frightening, read, despite the small shortcomings I mentioned.
