47、AI.He uses the example of having a robot do all your work for you and says“How cool that would be!”He also explains how AI could benefit us by listing various applications of AI,such as health care and machine translation.However,while looking forward to its potential,he is clearly concerned about t

48、he possible dangers of AI.He asks a series of questions about the future of AI and quotes Stephen Hawking to show the potential dangers.In the conclusion the author also warns,“We need to make sure that we will not fall victim to AI”.After watching a video,have a discussion.What is your attitude to
