Dorner Middle School in Ossining, New York, there’s a club called “Genius Bar” in the school library. It’s a help desk run by students, who can fix a computer, or even provide teachers with help in using new technology. This club has more than 20 members. Many people entered the library at lunch or other time of the day. The students have become a fix-it team for the rest of the neighborhood. For example, someone bought a new tech tool to use, but no one knew how to put it together. “So they posted it to us and the Genius Bar students put it together,” Allison Bacon, the person in charge (负责人), told the reporter. “Every week, new boxes of different things would appear, and people were like, ‘Hey, can you ask the kids to build this, or can you ask the kids to make this?’” Bacon said. When AI tools like ChatGPT came out, the Genius Bar kids were among the first to experiment with them. It almost became a group where students try out new things. It has also given some students suggestions about their future jobs. “I think we probably didn’t realize that we were so good at learning new technology,” said Owen Brennan, one of the club members. “But after this, we realized that maybe it’s something that we want to do as our career (职业) in the future.” 16.
