Whilst away on hockey tour in Malaysia I was able to avail myself of the ‘The Straits Times’ newspaper which is published in Singapore. One article that particularly caught my attention was that concerning the creativity of algorithms. Most are oblivious to their creativity yet highly sophisticated algorithms have created music based on the works of great artists but in a style that is personalised and therefore indicative of you the individual. They are also replacing writers – Professor Phil Parker of the Insead Business School in Paris has published more than a million reports on Amazon in just a couple of years. Using a proprietary algorithm that produces a report in 10 – 20 minutes instead of about 4 weeks. The algorithm pulls information from the web, performs econometric analyses, creates tables, formats the report and publishes it as a Word document. Professor Parker has also developed algorithms to produce poems, videos and video games.
Although we could question the efficacy of algorithms on intangible dimensions such as “soul’ and “depth”, one area where they trounce human beings is stock trading. With up to 75% of trades on Wall Street done using computer programmes it is no wonder that algorithms execute trade at lightening speed and carry out numerous transactions every second. On the NYSE the average round-trip transaction time is 600 microseconds. To put into perspective if you blinked it takes you 300 milliseconds to complete the action – during that time NYSE executed 500 trades. This desire to improve efficiency in the market has led to extremely low costs of trading and very high stock liquidity. However it has also produced huge swings in stock prices. On 6th May 2010 – know as the ‘Flash Crash’ – the DJIA fell 9% in minutes but then recovered most of that loss in the subsequent few minutes.
The landscape of society was always made up by this uneasy relationship between nature and man. But now there is this third co-evolutionary force – Algorithms – and we will have to understand them as nature and in a way they are. Kevin Slavin Ted Talk
