True, but why? Activision spends over $10M annually on employing an analytics team of about a dozen PhDs to build Rubin causal models to be able to show the right thing at the right time to players. That kind of budget makes sense for a $1 billion title like Call of Duty, but where does that leave the other 99%? The fact is that even for the companies that don't employ a full-time team of statisticians, if you're running your app or game like a true business you should be leveraging data to make better business decisions. Bandit algorithms like those we're proposing just let you do that at a fraction of the cost ;-)
