This essay argues the positive case for HFT and latency competition based on four main reasons: (1) Low latency trading lowers spreads, (2) Economically significant things do happen on sub-millisecond time scales, (3) HFT is the optimization layer for capitalism, and (4) Markets are not a zero-sum game. Latency plays a significant role in how humans interact with the world. When we perceive and respond to stimuli, there is an inherent delay between the occurrence of an event and our reaction to it. This delay, or latency, is typically around 200 milliseconds, which is the time it takes for light to enter the eye, be conver
