"today’s Wall Street is the first and perhaps only industry putting artificial intelligence toward actual productive ends" What are you talking about? Google (search, navigation, advertising), Amazon (recommendations), Facebook (advertising, whatever the hell else they do). 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). You are right though, Wall Street's applications are much more productive.
