> if it worked, they wouldn't be sharing it and would simply be printing money by taking advantage of it. Sure, there are some techniques in financial markets that are only valuable when they are not widely known. But claiming this pattern applies universally is incorrect. Publishing a technique doesn't prove it doesn't work. (Stating it this way makes it fairly obvious.) DeepMind, like many AI research labs, publish important and useful research. One might ask "is a lab leaving money off the table by publishing?". Perhaps a better question is "What 'game' is the lab playing and over what time scale?".
