Since ChatGPT’s explosive debut in November 2022, fears of robots replacing humans at work have been rampant. And according to Elon Musk, these fears are about to become very real, very soon.

The Tesla, SpaceX, and X app (formerly known as Twitter) boss just put doctors and surgeons on a three-year deadline before robots can not only do their jobs but also outnumber them in practices and hospitals. And his eyes, job losses aside, that’ll be a good thing for humanity:

“Everyone will have access to medical care that is better than what the President receives right now,” Musk said on the podcast Moonshots with Peter Diamandis.

“Right now there’s a shortage of doctors and great surgeons. It takes a super long time to learn to be a good doctor, and even then, the knowledge is constantly evolving. Doctors have limited time. They make mistakes.”

Musk pitched that his own Tesla Optimus robots will be the solution—despite previous hiccups and missed ambitious production targets. By 2030, he said, “there will probably be more Optimus robots that are great surgeons than there are all surgeons on Earth.”
