You want my 2 cents on this?  If anyone saw or remembers the movies "The Matrix" or "The Terminator" or "iRobot" those story tellers have portrayed scenarios of what could possibly happen when AI is left unchecked.  Corporate and Government greed could very well allow something of that magnitude to potentially happen.  So, if you are asking, am I afraid of the future of AI?  Your damn straight, I am!
