This quote and much more from Davos:

What happens at the World Economic Forum in Davos? : The New Yorker: He explained how Tibco, on behalf of Harrah’s, had designed a system that can figure out when a gambler is about to encounter a loss of such magnitude that it will cause him to leave the casino and perhaps never come back. The casino’s Luck Ambassadors will then offer the gambler a free meal or a ticket to a show (Tibco’s software having determined that there are otherwise empty seats to fill or excess inventory to slough off), and distract the gambler long enough to entice him to return later, to continue losing money in palatable increments. At the moment, he said, Tibco was building an engine that will mimic the way the human brain recognizes patterns.
