The widow of a man killed in a mass shooting at Florida State University is suing ChatGPT maker OpenAI, blaming the artificial intelligence chatbot for contributing to the tragedy. The lawsuit says the alleged gunman Phoenix Ikner relied on ChatGPT to determine what type of gun to use and which location would allow for the most potential victims, among other information. The lawsuit was filed by Vandana Joshi. Her husband was one of two people killed and six others were wounded. She said in a statement Monday that "OpenAI knew this would happen." OpenAI denies wrongdoing.
