The poker-playing AI is getting smarter and the humans are getting tired

Today begins week three of the poker tournament between Libratus, an AI system built by researchers from Carnegie Mellon University, and four of the world's top pros. While the humans plan to soldier on, a gallows humor has taken hold. With a little over 80,000 hands played, out of 120,000 total, the humans are down by roughly $750,000, a massive amount that will be all but impossible to come back from. "We're all down about the price of a small house," said Jason Les, chatting with onlookers about the score while he played. The players don't actually have to pay the AI anything, and in fact all get paid depending on how well they perform relative to one another. "It's not about the money, it's about preserving human dignity," quipped Les.
