But those are fiction, they are both have the robot characters. So it makes AI sound a little fictional to us. In fact, AI is not jus

2、t about robots, it exists everywhere.,Dictionaries define intelligence as the ability to acquire, understand and apply knowledge, or the ability to exercise thought and reason. Of course intelligence is more than this. It embodies all of the knowledge and feats, both conscious and unconscious, which

3、 we have acquired through studying.,What is artificial intelligence exactly?,Systems that think like humans,Systems that act like humans,Systems that think rationally,Systems that act rationally,Views of AI fall into four categories:,The exciting new effort to make computers thinks machine with mind

12、ys.,Artificial intelligence are not living organisms, so it cannot have feelings.,Agree Robots have replaced human beings in many aspects of work that people do, especially the dangerous work and some housework. This will probably happen gradually over a period of time, but it is an inevitable trend

13、.,Disagree Robots can only replace humans in doing some jobs, but: Made by people No human characteristics,Will robots ever be able to replace people?,Summarize,Artificial intelligence can be scripted as a new science and technology, which is used to simulate human intelligence. We cant deny the fact that artificial intelligence is of great important nowadays. Therefore, what we should do is to study hard, wid
