Elon Musk wants to give amputees robotic limbs powered by chips implanted in their brains

• Elon Musk floated an idea for a new line of Tesla products on Wednesday: robotic limbs.

• You read that right.

• Tesla is working on a humanoid robot. Musk thinks the tech could also be used to make prosthetics.

Between SpaceX rocket launches, visits to the Tesla production line, and serving up dank memes on Twitter, Elon Musk apparently has time to ponder new product ideas.

While updating investors on Tesla's second-quarter performance on Wednesday, the billionaire entrepreneur floated an idea for a new line of Tesla products: robotic limbs. You read that right.

The Muskiverse can be confusing and fast-moving, so let me bring you up to speed. At a Tesla event in late 2021, Musk said the carmaker was developing a human-like robot. The Tesla Bot would be 5-foot-8, walk 5 miles-per-hour, be powered by AI and cameras, and be able to relieve humans of the drudgery of factory work and other manual labor, Musk said. He added that we human overlords will be able to overpower the robot if needed, so that's nice.

Then in late 2022, while Musk was embroiled in a bitter fight to back out of his deal to buy Twitter, Tesla showed off an actual prototype. Musk has said that the robot program, dubbed the Optimus project, is the most important project Tesla is working on and that it could eventually make more money than its core car business. For Tesla investors, that's exciting.

That brings us back to robotic limbs.
