Forgot your password or your ID? Well, you'll never forget your face. Using your face as your ID is quick and convenient. You could take the subway or board a flight with just your face alone. This is how facial recognition(人脸识别）works. It has also been used to catch criminals. Taylor Swift even used the technology to identify stalkers (识别跟踪者) at her concerts.

In China, facial recognition systems have been used in many areas. In Zhengzhou, people can now get on the subway by using facial recognition technology. They just need to link their online payment systems to the subway's smartphone app. Students at Peking University can pass through the school's gate by scanning their faces.

However, many citizens are worried about the collection and use of this information by governments and companies. “I feel uncomfortable because I don't know how the company is using my facial details or whether they will be leaked (泄漏）,”Feng Yi, a tourism company employee, said. Leaks are a problem because there is a long history of companies failing to protect user data. When someone steals your personal information, you can change your bank card and password, but can you change your face when your facial information is stolen?

As facial recognition is used more and more in our daily lives - from college campuses and subways to street corners and smartphones - we must ask ourselves whether or not this new technology is worth the risk.

ChatGPT, a smart AI chatbot（聊天机器人） tool, has swept the education world in the past months. According to a US survey of 1,000 students, over 89 percent of them have used ChatGPT to help with their homework.

Developed by the US company OpenAI, ChatGPT is powerful. You can ask it to write stories and e-mails, create recipes and answer all kinds of questions.

Some schools in the US, Australia and France have banned the use of ChatGPT. In the US, for example. New York City public schools stopped students and teachers from using ChatGPT on the district’s networks and devices.

The move comes out of worries that the tool could make it easier for students to cheat on assignments. Some also worry that ChatGPT could be used to spread wrong information. Apart from bans, teachers are making changes to their classes to prevent the use of ChatGPT. Some college teachers in the US try to include more speaking exams and handwritten papers instead of typed ones.

However, not all educators say “no” to ChatGPT. Some Canadian universities are making policies on its use, for both students and teachers. They have no plans to completely ban the tool so far.

Bhaskar Vira, the headmaster at Cambridge University in the UK, said that bans on AI software like ChatGPT are not wise. “We have to know that AI is a tool people will use,” he told the school newspaper of the university. What we need to do is adapt（使适合） our learning, teaching and examinations. That way, we can have honesty while recognizing the use of the tool.

Are robots going to take over the world? This was one of the biggest fears people had about the development of technology. But since then, those fears have been largely replaced by COVID19. Now, more and more people are beginning to regard robots as a useful solution for social distancing problems.

Robots have been used for years, even though you might not connect these tasks with robots. ATMS in banks are common examples of everyday robots. There are many companies using robots even before the pandemic (疫情). Robots have also been used for tasks considered dangerous.

Among COVID-19 conditions, new robots are being tested in many fields. At McDonald’s and other fast food restaurants, robots are being tried as waiters and even cooks. Restaurants are using robots to send their food safely to homes of old people because they’re at high risk from COVID-19. Disinfection (消毒) robots have been developed to fight against COVID-19 in Qingdao, Shandong Province. They can replace human beings in carrying on the responsibility of disinfection. These newly developed disinfection robots have been put into operations in the quarantine wards (隔离病房) of some hospitals.

The arguments against robots include the loss of human jobs and the idea that machines could control our lives. But now that COVID-19 has changed the world, more people will likely be accepting robots. The situation now is showing us how technology can be used to improve the world.
