AI researchers ran a secret experiment on Reddit users to see if they could change their minds — and the results are creepy

Reddit is threatening to sue a group of researchers who used artificial intelligence (AI) chatbots to secretly experiment on its users.

Scientists from the University of Zurich set loose an army of AI bots on the popular Reddit forum r/changemyview — where nearly 4 million users congregate to debate contentious topics — to investigate whether the tech could be used to influence public opinion.
