The relentless pursuit of speed in financial markets has pushed trading technology to its absolute limits. Professional traders now execute thousands of trades per second, creating a technological arms race where firms minimize wire lengths to exchange computers. This evolution has fundamentally transformed market dynamics, favoring players with the deepest pockets for infrastructure.

University of Edinburgh sociology professor Donald Mackenzie has extensively studied this phenomenon, documenting how finance and technology intersect in his 2021 book "Trading at the Speed of Light." His research reveals how trading floors evolved from open outcry to electronic systems, with each technological leap further concentrating advantages among well-capitalized market participants.

The concentration of technological advantage raises serious questions about market fairness and accessibility. As Mackenzie's work demonstrates, the gap between institutional capabilities and individual investors continues to widen, potentially reshaping market structure for years to come.
