"today’s Wall Street is the first and perhaps only industry putting artificial intelligence toward actual productive ends"<p>What are you talking about?<p>Google (search, navigation, advertising), Amazon (recommendations), Facebook (advertising, whatever the hell else they do).<p>The United States Military (robotics, autonomous drones, scheduling, pretty much all AI applications). UPS (scheduling). NSA (data mining metadata to detect 'em terrorists), NASA (control systems, detection of objects).<p>You are right though, Wall Street's applications are much more productive.
