Speaking to him, the billionaire told the crowd that “violence is coming” and that “you either fight back or you die”.The Liberal Democrat leader, Ed Davey, said: “Elon Musk openly called for violence on our streets yesterday. I hope politicians from all parties come together to condemn his deeply dangerous and irresponsible rhetoric.”Asked on the BBC on Sunday whether the tech billionaire was trying to incite violence, the business secretary, Peter Kyle, said: “I thought that they were slightly incomprehensible comments that were totally inappropriate.”Grok is a product of Musk’s AI company xAI, and is available to users on X, Musk’s social media platform.
