On Sunday night, Elon Musk revealed in an X Spaces with Dr. Gad Saad, a professor of marketing at the John Molson School of Business at Montreal's Concordia University, that two "very mentally ill" people have tried to kill him in Austin, Texas. 

Near the end of the one-hour interview, Musk discussed his level of fame and how it's been problematic when he goes out in public. He said people are super nice, but every time he goes to restaurants, there are lines of people who want selfies with him. 

"I can't easily go to the mall or a movie theater or walk around without creating a ruckus," the world's richest man said.
