In his 2014 book "Flash Boys", American Author Michael Lewis, details the mass adoption and consequences of High-Frequency Trading or HFT
High-frequency trading is the process of executing mass amounts of stock trades, based on complex algorithms, in fractions of a second
This enabled buying and selling at a speed that no human could match, and it made big investment banks such as Goldman Sachs a lot of money
But, it also caused the flash crash in May 2010, when the US Stock market dropped and subsequently recovered almost $1 trillion in the space of just 36 minutes, and all we humans could do was watch and panic
If that doesn't scare you, imagine what happens when AI starts making trading decisions
