Tesla hosts its ‘We, Robot’ event on Thursday at Warner Bros. Discovery’s movie studio in Burbank, California. Elon Musk said the company has made a lot of progress on its Optimus robot and that it will eventually cost between $20,000 and $30,000. He said it will be able to “be a teacher, babysit your kids, walk your dog, mow your lawn, get the groceries…Whatever you can think of it will do.” The robots walked among the crowd at the event.
