“Quants” are the mathematicians, software developers and computer programmers at the centre of the global economy. These are the people who designed the “complex financial products” that caused the financial crisis of 2008. Here they speak openly about their game of huge profits, and how the global economy has become increasingly dependent on mathematical models that quantify commodified human behaviours to the point of insanity. But things don’t stop there. Through the convergence of economy and technology, the Quants have now brought this model into the world of the machines, where trades are done at the speed of light, far from the realm of human experience. The machines are in charge. Some Quants are even now worried. What are the risks of this complex machine? Will the Quants be able to keep control of this financial system, or have they created a monster?
