The same could be said of HFT. Traders are "skilled" at having nanosecond access to the orderbook, having their servers co-located in the same rack space as the exchange itself. They are also "skilled" at recognizing a price movement nanoseconds before it actually happens and getting their order in just in time.
But the HFT game changes and you have to keep up. Just as a poker player from 10 years ago would not survive in the game today without adapting his style of play.
