Questions & Answers

Q: What is the role of algorithms in finance and how do they affect the stock market?

Algorithms are used in finance to break up big transactions, but they can also lead to market crashes, such as the flash crash of 2009, where 9% of the market disappeared in minutes without any control or understanding of what happened.

Q: How do algorithms influence the film and entertainment industry?

Algorithms are used by companies like Netflix to recommend movies to users, with one algorithm being responsible for 60% of movie rentals. There are also algorithms that can predict the success and cost of movie scripts, affecting the types of films that get made.

Q: Are algorithms only present in the financial and entertainment industries?

No, algorithms are present in various aspects of our lives, including cleaning robots competing for dominance in our homes. They also impact architecture design, with algorithms optimizing elevator systems for efficiency but causing panic among users due to a lack of traditional controls.

Q: What are the potential consequences of relying on algorithms to shape our world?

The reliance on algorithms can lead to unexpected and uncontrollable outcomes, as seen in market crashes and conflicting algorithms on platforms like Amazon. It raises concerns about our ability to understand and navigate a world shaped by algorithms that we no longer fully comprehend.

Summary & Key Takeaways

• Artist Michael Najjar digitally reshapes mountains in his photograph to mirror the Dow Jones index during the 2008 financial crisis.

• Algorithms, especially those used in finance and technology, are transitioning from being derived from the world to shaping the world.

• Wall Street employs over 2,000 physicists who use algorithms to break up large transactions, but this can lead to unpredictable market behavior.
