Algorithmic arms race on Wall Street -- goodbye traders

Short, overview article on how even the more conservative, traditional firms are on the bandwagon now. Traders are becoming irrelevant. The IBM study mentioned is here (haven't read).
Also, this Institutional Investor article more specifically covering dark pools and algorithms for trading execution efficiency, rather than for strategy (I read some headline somewhere about applying peer-to-peer tech to orders). There's a lot of in-house order routing to dark books going on; not necessarily getting the best price in the world. There seems to be less and less point to a displayed, depth quote screen.
Regulation cannot help but lag.
