"High-frequency trading" (HFT) has gone from a financial industry dark art to newspaper and blog headline-fodder over the last few days, and for good reason. The practice, which relies on networked computers to execute billions of micro-scale transactions in order to sniff out prices and beat out slower traders, has all of the earmarks of a Very Bad Thing, indeed: exploitation of pre-computerized trading rules; possible out-and-out illegal activity ("front-running"); and systems operating too fast for any human to oversee, let alone counter. . .
HFT systems were designed to operate in an environment where even the lowliest day-traders had access to powerful computers and high-bandwidth connections. That is, the competition for HFT isn't just the human making buy and sell decisions, but the computerized system augmenting that trader: popping up alerts, executing buy and sell orders based on pre-arranged triggers, and gradually reducing the number of decisions the human operating needs to make over the course of a trading session. It's an arms race, of sorts, and one that wasn't anywhere near ending. . .
So here's where the parallel to military systems becomes clear. Right now, the tactical awareness and decision-making used by military robots and computers operates, by and large, at human speeds. It may seem like a split-second decision has to be made when a Reaper identifies a potential target and transmits that data via satellite to controllers in the US, who then have to decide whether or not to pull the trigger, but from a computer's point of view, that decision-making period--perhaps taking as much as a minute -- means millions of cycles of just doing nothing, waiting for the human minds to act. . .
