From the Asian and Russian currency crises from 1997 onward, many financial gurus described the sudden bubble pops as caused by too much money chasing too few solid opportunities.Â
A great deal of financial decision making is now done by computer models, from personal credit scores to trading of investment instruments, like CDOs, credit default swaps, etc.Â
The newest financial trading models are poised to rev up transaction speed even higher.  High frequency trading (HFT)is already reported to be at intervals of 1/1000th of a second. When a new computerized trading center opens it will take HFT to a new level, and dueling trading models already account for about 90% of all trades. It may soon rise to say, 99% -- or all trading will be by computers.
The churn speed of these transactions may change the nature of markets. They can spiral too quickly for human intervention, so controlling computers will have to intervene on human's behalf.Â
