This is the first job that a robot can take over. Burger-flipping robot begins first shift Is it possible robots can take over humans in the future? Are you the kind of person that says don't worry about it, who makes the robots?
Lots of jobs have been taken over by robots already and the trend will continue. Some companies have replaced most of their workforce with robots. In Japan, I think, they have a restaurant ran entirely by robots. They also plan on using robots to take care of their elderly in the near future. Farms are starting to use them also. The day will come soon very few farm workers will be needed.
Am I afraid of them, only in the sense what jobs are people going to do. Some countries are talking about giving people a basic income because of it. I hope people are smart enough not to give them too much free will.
