阅读理解：Since the AI chatbot(一种聊天程序) ChatGPT was released in 2020, we've been hearing about the threat posed by artificial intelligence. A statement signed by academic experts and tech industry figures even branded(贴标签) AI an “extinction risk”. In education, there have been concerns that ChatGPT could negatively affect the learning process of students. For example, students could ask ChatGPT to write their coursework for them, skipping the research and writing effort that leads to a better understanding of the topic in question. Perhaps a better method would be to change and enhance(提高) how we teach and assess(评估) the outcomes of learning. Making education more focused on practical skills and the use of knowledge in problem - solving could ensure a deeper understanding on the part of students. AI could be used for guidance, in much the same way we currently use calculators(计算器), to help enrich people's knowledge. However, risks do exist. In May 2023, for example, a US lawyer admitted using ChatGPT for case research. The lawyer's filing(存档档案) was found to reference legal(合法的) cases that didn't exist. The chatbot had made them up. It's not the first time that these “AI hallucinations(幻觉)” have been reported. Then we have the very real risk that AI could be used for illegal purposes such as identity (ID) theft. For example, criminals could use AI to clone someone's voice. They could then phone family members and try to convince(说服) them to give out sensitive information that could be helpful for accessing bank accounts. A variant(变种) of AI - driven identity theft is the use of deepfake(深度伪造的) videos. However, Bill Gates, the Microsoft co - founder, sounds less worried than some other executives(领导层) in Silicon Valley about the risks of artificial intelligence. In a blog post on Tuesday, he wrote, “This is not the first time a major innovation(创新) has introduced new threats(威胁) that had to be controlled. We've done it before.”
