2、ligence(AI)_ cloning 2.Discuss these questions in groups.How do you think these events or such technology might develop in the future?What challenges might they bring?What opportunities might they bring?Listen for predictionsWhen listening for predictions,you should listen for the use of the future

3、tense,in particular the future tense with will or will be doing.Words such as predict,prediction,and forecast,are also used quite often when making predictions.How do you think these events or such technology might develop in the future?No doubt,AI will develop to the point that humans and computers

4、 will be able to interface effortlessly.With the development of AI,there may come a time when it becomes a real issue as to whether a computer or machine has in fact achieved consciousness,and whether,as a conscious being,it deserves the same rights as a human being.What challenges might they bring?

5、What opportunities might they bring?AI may help us solve problems that arecurrently too big and overwhelming forus to solve on our own.For example,complex AI models may be able to use given data to develop a workablesolution to global warming.3.Listen to a radio interview with Dr Han and Vincent Bla

19、who need transplant.A:Well,that would be really good news for all of us.Could you please explain how this will be possible?B:Well,it will be possible because of special 3D printers.In the future,doctors will be using them in hospitals regularly to create healthy copies of peoples organs.Then they will replace the unhealthy organs with the healthy copies.
