You may think this is a talk between two people. But what if B is a robot? This is ChutGPT. It is a clever AI chatbot（聊天机器人） made by a US company. It can do a lot of things. I can answer questions, even open- ended ones. For example, "What's the meaning of life or "It's 40℃ out today. What should I wear?" It can give people a movie review in the style of Shakespeare. It can write emails, essays and code.
ChatGPT is smart. Can students use it for their homework? In Australia and the US, some primary schools ban it on school computers. Teachers worry about students cheating（作弊） on homework.
ChatGPT's knowledge（学识） and its way of talking amaze people. But the robot has its problems. It can only answer questions with information in its database（数据库）. It is not good at thinking or being creative like people.
