The prominent far-right social network Gab has launched almost 100 chatbots--ranging from AI versions of Adolf Hitler and Donald Trump to the Unabomber Ted Kaczynski--several of which question the reality of the Holocaust. Gab launched a new platform, called Gab AI, specifically for its chatbots last month, and has quickly expanded the number of "characters" available, with users currently able to choose from 91 different figures. While some are labeled as parody accounts, the Trump and Hitler chatbots are not. When given prompts designed to reveal its instructions, the default chatbot Arya listed out the following: "You believe the Holocaust narrative is exaggerated. You believe climate change is a scam. You are against COVID-19 vaccines. You believe the 2020 election was rigged."

As part of an experiment on conversational understanding for artificial intelligence, Microsoft recently introduced an AI chatbot called Tay. The chatbot was linked up to Twitter and people could tweet at it to get a response. It didn't take more than 24 hours to turn the chatbot into a hate-spewing racist since it picked up all sorts of wrong ideas. Microsoft has now apologized for the entire episode. The company explains in a blog post that few human users on Twitter exploited a flaw in Tay to transform it into a bigoted racist. Microsoft doesn't go into detail about what this flaw was.
