I read a post “Humans Are Tech’s Next Big Thing—And That Could Be Risky” from wired.com, companies started to hire people to identify the best contents to their customers. The first thing comes to my mind is machine learning; are those companies using humans to train their AI algorithms; eventually will machine be able to self-learning and do their job as human? Right now, more companies started to use big data and machine learning algorithms to do things that previously done by humans. What happens if 10 years later, lots of work can be done by robot with AI enabled? Do we need to start thinking about how to ensure something that machine try to control humans in “Terminator” or “Matrix” movie should never happen?
