Neuralink

As of 2020, Neuralink has its headquarters in the Mission District of San Fransisco, sharing the former Pioneer Trunk Factory building with OpenAI- another company that Musk co-founds.

Even though Musk didn't hold an executive position, he majorly owned Neuralink, as of September 2018. Instead, Jared Birchall was listed for the post of being the president of Neuralink, along with CEO and CFO, in 2018.

However, a tweet in August 2020 had confirmed previous reports that Musk is the present CEO of Neuralink now. The company's trademark was purchased in January 2017, from its previous owners.

The technology proposed to be used in the future involves the placement of a module outside the highest point where it can wirelessly receive information from electrode threads which are thin and flexible and are embedded within our brains.

Musk claimed that the Neuralink is a "kind of a Fitbit in your skull with tiny wires". It has a robotic apparatus that embeds the threads in order to prevent the damage of blood vessels in the body.

Currently, the electrodes are still said to be too big to be able to record the firing off an individual neuron; so as that they're reaching to record alone the firing of a gaggle of neurons. The representatives of Neuralink believe that they can algorithmically mitigate the issue. However, it is expensive computationally and doesn't produce exact, precise results.

As of 2017, there are some neuroprosthetics which can interpret brain signals and allow people with disabilities to regulate their prosthetic limbs (arms and legs both).
