No bull -- AI investing is coming to Wall Street

Artificial intelligence has held great promise for decades now. Since the 1950s, experts have been predicting that the day when computers would think like humans was just around the corner. By the 1970s, as one system after another failed the Turing Test, artificial intelligence research fell out of favor -- the hype largely deflated by the influential book "Perceptrons," by Seymour Papert and Marvin Minsky. Recently, however, a series of advances in computing and so-called machine learning has triggered renewed interest in the potential of artificial intelligence. And while computers might not (yet) be self-aware or able to think like human beings, they becoming very good at learning how to diagnose diseases, find and defend against malware -- and beat humans at games of chess and Go.
