By MIKE CATALINI The highly decorated soldier who exploded a Tesla Cybertruck outside the Trump hotel in Las Vegas used generative AI including ChatGPT to help plan the attack, Las Vegas police said Tuesday. Nearly a week after 37-year-old Matthew Livelsberger fatally shot himself, officials said according to writings, he didn’t intend to kill anyone else. An investigation of Livelsberger’s searches through ChatGPT indicate he was looking for information on explosive targets, the speed at which certain rounds of ammunition would travel and whether fireworks were legal in Arizona.
