Robots are no joke
Some of these jobs, unfortunately, really are better served by robots. Others like pilot, journalist, and pharmacist will become a hybrid -- some automation but mostly human. But the ones that can outright replace humans will do so (sailor, farm worker, warehouse worker). It's easy to say: 'Let the robots do the jobs we don't want if they can do them more cheaply and efficiently.' But there's just so many of us and we all need to work. People rendered useless by robotics will be forced to a life on the fringes, possibly crime.
Robotics and automation are increasingly hot topics. Google's acquisitions, Jeff Bezo's drones tease on 60 Minutes, rampant tech innovation and a sluggish economy are pushing the conversation forward. Five years ago, you joked about a robot taking your job. Now it's not so funny.
