A new artificial intelligence (AI) tool called ChatGPT has excited the Internet community with its superhuman abilities to solve math problems, produce college articles and write research papers. Some educators are warning that such Al systems will change the world of learning, teaching, and research, for better or worse.

Ethan Mollick, a professor at the University of Pennsylvania’s Wharton School of Business, sees its benefits as a learning partner. He has used it as his own teacher’s assistant, for help with preparing a lecture and grading instructions for MBA students. “You can ask it to find a mistake in your writing and correct it and tell you why you got it wrong,” he said. “It’s really amazing.”

But the superhuman assistant has its limitations (局限). ChatGPT was created by humans, after all. OpenAI has trained the tool using a large dataset of real human conversations. It sometimes lies to you, with confidence. There have been situations in which ChatGPT won’t tell you when it doesn’t have the answer.

That’s what Teresa Kubacka, a data scientist based in Zurich, Switzerland, found when she experimented with the language model. “I asked it about something that I thought that I know doesn’t exist (存在) so that I can judge whether it actually also has the idea of what exists and what doesn’t exist.” she said. ChatGPT produced an answer so specific sounding, backed with citations (引文), that Kubacka had to find out whether the made-up thing was actually real. “This is where it becomes kind of dangerous,” she said.

ChatGPT doesn’t produce good science, says Oren Etzioni, the founding CEO of the Allen Institute for AI. But he sees ChatGPT’s appearance as a good thing. He sees this as a moment for review. “ChatGPT is just a few days old, I like to say,” said Etzioni. “It’s giving us a chance to understand what he can and cannot do and to begin the conversation of ‘What are we going to do about it?’”
