That's true - when HFT first became a thing, there were a few studies that compared reaction times between the top traders and the machines and found that expert traders that composed the market making function could make better trades in less time (on the order of fractions of a second) with fewer errors. Of course, that's a distant memory at this point -- the machines have obviously won out on the part of the market's structure but kind of interesting that the humans were quite fast (faster than I would have guessed).
