AI Can Now Debate with Humans and Sometimes Convince Them, Too

Today on the Science Talk podcast, Noam Slonim of IBM Research speaks to Scientific American about an impressive feat of computer engineering: an AI-powered autonomous system that can engage in complex debate with humans over issues ranging from subsidizing preschool and the merit of space exploration to the pros and cons of genetic engineering.  In a new Nature paper, Slonim and his colleagues show that across 80 debate topics, Project Debater’s computational argument technology has performed very decently—with a human audience being the judge of that. “However, it is still somewhat inferior on average to the results obtained by expert human debaters,” Slonim says.  In a 2019 San Francisco showcase, the system went head-to-head with expert debater Harish Natarajan.  Beyond gaming, it’s rare to see humans and machines go against each other, let alone in an oratory competition. Not unlike its human counterpart, the AI was given only 15 minutes to research the topic and prepar...
