Financial trading bots have fascinating similarities to people – we need to learn from them

In 2019, the world fretted that algorithms now know us better than we know ourselves. No concept captures this better than surveillance capitalism, a term coined by American writer Shoshana Zuboff to describe a bleak new era in which the likes of Facebook and Google provide popular services while their algorithms hawk our digital traces. Surprisingly, Zuboff's concern doesn't extend to the algorithms in financial markets that have replaced many of the humans on trading floors. Automated algorithmic trading took off around the beginning of the 21st century, first in the US but soon in Europe as well. One important driver was high-frequency trading, which runs at blinding speeds, down to billionths of a second.
