1 . The poster child for generative Ai software is a shocking human mimic. It represents a potential new era in research, but brings risks.

It co-wrote scientific papers-sometimes secretly. It drafted outlines for presentations, proposals and classes, churned out computer code, and served as a sounding board for research ideas. It also invented references, made up facts and repeated hate speech. Most of all, it caught people’s imaginations. ChatGPT took on whatever role its interlocutors desired—and some they didn’t.

ChatGPT’s only objective is to plausibly continue dialogues in the style of its training data. But in doing so, it and other generative artificial-intelligence(AI) programme are changing how scientists work. They have also reopened debates about the limits of AI, the nature of human intelligence and how best to adjust the interaction between the two.

For some researchers ChatGPT has become an invaluable lab assistant—helping to summarize or write manuscripts, polish applications and write codes. ChatGPT and related software can help to brainstorm ideas, enhance scientific search engines and identify research gaps in the literature, says Marinka Zitnik, who works on AI for medical research at Harvard Medical School in Boston, Massachusetts.

But the technology is also dangerous. Automated conversational agents can aid cheats and plagiarists; left unchecked, they could damage the well of scientific knowledge. Undisclosed AI-made content has begun to spread through the Internet and some scientists have admitted using ChatGPT to generate articles without declaring it.

No one knows how much more there is to get from ChatGPT-like systems. Their capabilities might yet be limited by the availability of computing power or new training data. But the generative AI revolution has started. And there’s no turning back.

Although the tanghulu idea was widely praised, it wasn’t enough to represent the image of a big country. So the team tried again and again, changing the image in the ice shell into elk, tiger, rabbit…Various ideas have been put forward and overturned, but eventually it was decided that China’s national treasure panda is the most beloved by people all over the world.
