The hallmark of our world is change. Every aspect of our lives is constantly disruptive by innovations and new technologies. According to history, every disruptive innovation is tailed by its fair share of treats and irrational concerns. Nevertheless no period in mankind history has any major change been greeted with as much fear as this age.
Humans rule the world not because we are the strongest but because we are the smartest. What happens when we lose that position to machines? How about the millions of jobs that would be lost? How do you imagine AI as autonomous weapons in the wrong hands?
More disturbing is the growing apprehension of redundancy of many who today work in the millions of jobs that may be unnecessary as robots and AI perform the same functions far more efficiently and even cheaper. What happens to pensions of retired humans when the majority of current workers are robots who earn nothing.
AI, a concept whose time has come, has come to stay. It's just a matter of time.
