You will lose your job to a robot--and sooner than you think

I want to tell you straight off what this story is about: Sometime in the next 40 years, robots are going to take your job. I don't care what your job is. If you dig ditches, a robot will dig them better. If you're a magazine writer, a robot will write your articles better. If you're a doctor, IBM's Watson will no longer "assist" you in finding the right diagnosis from its database of millions of case studies and journal articles. It will just be a better doctor than you. Robots will run companies better than you do. Robots will paint and write and sculpt better than you. Think you have social skills that no robot can match? Within 20 years, maybe half of you will be out of jobs. A couple of decades after that, most of the rest of you will be out of jobs. In one sense, this all sounds great. Let the robots have the damn jobs! We'll be free to read or write poetry or play video games or whatever we want to do.
