    For two centuries, the famous University of Cambridge debating society has hosted many prominent figures, from world leaders to scientists to comedians.

On Nov 21, the Cambridge Union hosted another extraordinary guest—a non-human debater called Project Debater. Designed by IBM, Project Debater is a machine that uses Artificial Intelligence (AI) to form a spoken argument. It can even listen and answer to opposite statements, much like a real person.

In the Cambridge test debate, it argued the topic: Al will ultimately (最终) do more harm than good. Before the debate, more than 1,100 arguments for the positives and negatives of AI were submitted (递交) to the IBM website. The machine then analyzed these sources and formed the basis of its arguments in minutes. Project Debater then showed off its AI by arguing for both sides of the debate.

Over a four-minute speech, it argued first that, “AI can only make decisions that it has been programmed to solve, while humans can be programmed for all situations.”

In support of AI, it then argued that AI would create new jobs and “bring a lot more efficiency” to the workplace.

This isn’t the first test for Project Debater. In June 2018, the machine went back-and-forth for 20 minutes against champion debater Harish Natarajan.

According to New Scientist, on both occasions, Project Debater repeated points and didn’t always sufficiently (充分地) support them.

Speaking to Cambridge Independent, Noam Slonim, the project’s lead engineer, said, “The AI is not perfect, but it’s going in the right direction.” The team hopes to improve the AI by researching why humans find certain arguments more persuasive than others. They also hope the test might provide well-informed viewpoints for society, governments and private companies.
