It has long been the development of artificial intelligence. We've all seen the movie "Terminator" and we know where it may lead. On the other hand for a person is very attractive to shift all the work to robots. You for which option?
I think this would be for the better of people's lives. We shouldn't br afraid of ai as i think scientists are very well aware of the dangers and would have contingency if ever they become hostile which is very unlikely. People still hold power over machines and i don't think it's going to be like in the movies.
