In the fourth episode of Endless Thread's series "Good Bot, Bad Bot," co-hosts Ben Brock Johnson and Quincy Walters share a cautionary tale about Tay, a Microsoft AI chatbot that has lived on in infamy. Tay was originally modeled to be the bot-girl-next-door. But after only 16 hours on Twitter, Tay was shut down for regurgitating white supremacist, racist and sexist talking points online. Tay's short-lived run on the internet illuminated ethical issues in tech culture. This episode uncovers who gets a say in what we build, how developers build it, and who is to blame when things take a dark turn.
