Elon Musk shows off bartending robots at a recent Tesla event, but some attendees say the automatons were being controlled by people

In 2021, Elon Musk unveiled a humanoid robot that turned out to be a guy in a suit. A year later, we got a look at a prototype version of the robot—not a guy in a suit this time—which we said was “kind of neat” thanks primarily to its ability to walk around slowly without falling over. At a Tesla event called We, Robot last night, Musk trotted out a whole squad of the machines, alongside some absolutely wild promises about what they’ll be able to do.

“It’ll be able to do anything you want,” Musk said during the presentation. “It can be a teacher or babysit your kids. It can walk your dog, mow your lawn, get the groceries. Just be your friend—serve drinks, whatever you can think of, it will do. It’s gonna be awesome. I think this will be the biggest product ever, of any kind. Because I think everyone, of the eight billion people on Earth, everyone, they’re gonna want their Optimus buddy. Maybe two.
