Who do you think created HFT (High Frequency Trading) systems? Surely bankers stick to banking but hire developers to give them that competitive edge. The odds are that software engineers would have come up with the idea of and implementation of, a working high frequency trading system before bankers would have despite banking probably not being a software engineer's specialty.

I think market makers used technology to do exactly what they've always done at increasingly higher speeds. History also shows you're wrong, for hundreds of years market makers have sought an edge by trying to get information faster and faster. Hell, it used to be carrier pigeons that gave them the edge. There's really not much new here...
