At a show and tell event on Wednesday, Musk said that Neuralink could implant one of its devices in someone's head within six months. At some point in the future, he claimed, he would have the device implanted in his own head.

The company submitted most of the paperwork needed for a human clinical trial to the FDA, according to Musk. Musk had previously stated that he wanted human trials to start in 2020. At least 2023 is when that will slip to.

Neuralink wants to create a device that can be implanted in the brain and used to control a computer. The company was testing its device in monkeys. The pigs had the implants. Last year, Neuralink showed a monkey playing a game with its brain. One of them helped type the phrase 'welcome to show and tell' using their implant by focusing on highlighted words. A video shows how the monkeys were trained to charge their devices.

Neuralink researchers showed off a pig on a treadmill in order to study how to address mobility issues in the future.

The Neuralink devices are small and can be put into the brain. It's like replacing a piece of your skull with a wristwatch for lack of a better analogy.

In about 15 minutes, 64 of these threads can be implanted into the brain using a robotic system.

There is a reason for the robot surgeons. Christine Odabashian, the leader of Neuralink's hardware insertion team, said that it was possible to take a hair from a person's head and stick it into jello.

In the past two years, the company has held demos as recruitment events, and this one is no different. Musk said Neuralink is looking to fill many different kinds of jobs as it moves from type to product.

There was a technical presentation of the device, showcasing how the system was built, challenges the team has faced, how the tech has improved, and what developments are coming next. The company's researchers said they were working on treatments that could help improve or restore vision in people with paralysis. The company wants the device to be easy to upgrade.
