1 . The development of artificial intelligence (AI，人工智能)is a hot topic these days. AI makes it possible for machines to learn from experience and perform human-like tasks. But what is the future of AI? Will it be a good thing? We asked students what they think.

I think AI will be more useful in our future lives. It’s now used in many fields like phones and medicine. No one really knows what will happen if machines become smarter than humans. However, I’m sure AI will help us solve problems. Tina

I am worried that people create something that can be better than themselves. In the near future, AI will develop at a high speed. Humans may be replaced because AI robots will do lots of human jobs. Bill

I really think that AI will change the way we work, the way we live, and the way we think. Imagine if we could. put a CPU (中央处理器)into our brains! Soon we’ll be able to improve our math and memory. How exciting! Mary

Think of what’s happening right now. Some robots are used to kill animals under human orders. So I think AI will be very dangerous for humans. We need to be careful about what we ask machines to do. John
