Conclusion

To sum up, the dependence on robot of human is getting higher as the robot technology develop dynamically. According to Book: Race Against the Machine by MIT economists Erik Brynjolfsson and Andrew McAfee, human's job is threatened by robot technology, and unemployment rate of laborer and technology development are related. Moreover, many robots already take many our jobs today.  Although there is a job which humans can do but robots and AI can’t and many new jobs will be invented in the future, people whose job is dependent on labor will loss their jobs. The researchers argue that the technology boom can explains about half the drop in labor's share of the world's economy. That's great for stockholders. It's great for consumers, who get better, cheaper products. It might even be great for workers with the skills to thrive in the today's labor market. But it means we also need to think of ways to take care of the casualties of our high-tech economy. These changes, after all, aren't going away.
