Elon Musk’s Neuralink brain-machine interface is turning sci-fi into reality

Besides giving the world the option to switch to Tesla emissions-free electric cars and hopes of sending humans to Mars and beyond, Elon Musk also dreams of giving humans symbiosis with artificial intelligence through an implantable brain-machine interface created by Neuralink, a company he founded in 2016.

Neuralink is working on improving the basic structures of high-density Utah Array, a tiny chip that has become the industry benchmark for recording large populations of neurons. Dr. Richard Norman from the University of Utah invented the chip in 1997, which acts as an ultra-thin, flexible, and biocompatible polymer that connects the human brain to a tiny chip. During an event last year, Neurallink explained that the implant can be placed behind the ear and can interpret brain signals. Musk’s neural tech company has also invented a robot that can sew the implant to the brain with better precision than any human surgeon.

So far, the brain-machine interface by Neuralink has reportedly helped a primate communicate with a computer interface. There are plans to install a prototype this year into a human. According to Musk, they are still on track to do this.

“It will ultimately be used to make up for entire lost sections of the brain due to stroke/accident/congenital. Don’t want to get too excited, but the potential is truly transformational for restoring brain & motor functions. There is no other way to do it imo,” Musk also wrote on Twitter.

The possibilities for Neuralink’s implant are endless. The symbiosis between humans and AI will be a long shot but Neuralink’s implantable device can pave the way for medical advancements that can help people with chronic neurological problems.  Possible medical uses for Neuralink’s device in the future include controlling devices, restoring sensation, and synthetic speech.

CONTROLLING DEVICES

The brain is a complex network of nerves that uses impulses to sense the outside world and to control the human body. Neuralink will use these signals and amplify them so a patient can use them to be more functional. For example, someone with paralyzed upper extremity due to a stroke can have a brain-machine interface on the center of the brain that controls movements of the arm and hands which will help patients feed, dress, and generally function on their own.

Likewise, for someone who has an amputated limb, the Neuralink brain-machine interface will be able to communicate with a robotic arm to help someone use an artificial hand to write or use a computer. It can also be perfect for someone who needs to control a robotic leg to prop one up to stand without the help of anyone.

With a smart home setup, a paralyzed person who cannot clearly or is unable to speak and move can simply command a computer to dim the lights, turn on the air conditioner, or call someone if they need urgent attention.

While it might be a very long shot, these brain-machine interfaces interacting with other future technologies can also serve as bridges to parts of the body that are medically “disconnected”. For example, a patient with spinal cord injury has severed connections between the brain and parts of their body corresponding to the level their spinal cord was injured. The Neuralink implant can play pseudo stem cells that will provide the artificial connection so one can better function. Same for someone with multiple sclerosis whose nerves basically lose the sheath that makes them transmit electrical signals optimally.

“RESTORE” SENSATION

Just like how Neuralink can be exploited to help the brain control movement of a robotic arm, it is highly possible to tap into the sensory cortex of the brain. Sensation allows better manipulation of one’s environment and should be very helpful even when using robotic arms. One can tap the signals of the brain, send it to the brain-machine implant and to the robotic hand, for example, and back. If one grabs a glass of water, it can easily control the movement through space because the patient knows its shape, weight, texture, temperature, among other factors.

The Neuralink team also aims to use the brain-machine interface to “give back” one’s vision by tapping into the visual center of the brain.

SYNTHETIC SPEECH

With its ability to tap into specific signals of the brain, Neuralink also has the potential to create synthetic speech for people who are paralyzed or those with neurological conditions that do not allow them to speak.

These are just some of the things we can see Neuralink will be used for in the future. While all these seem to be fantastical, according to Neuralink, what they’re doing is not pulled from thin air but based on decades of neurological foundation.

Ultimately, with the dream of human-AI symbiosis, as more technologies develop, the use for Neuralink’s brain-machine implant will evolve. Elon Musk mentioned before that perhaps one day, it will be used for telepathic communication between humans or perhaps even drive a Tesla. Or perhaps, in the future, one can upgrade one’s knowledge and download terabytes of information with a blink of an eye through Starlink.

Tesla has created a clever solution to simplify and improve its Service. Tesla performs most of the services that are needed on its vehicles at its company-owned Service Centers.

However, service has been a weak point of the company, as some regions have fewer Service Centers than others. This can cause long wait times for Tesla owners in some parts of the country.

There are also instances where customers do not agree with what Tesla is saying about their vehicle. In fact, one instance that revealed this new change Tesla is making to its Service was precisely that.

One owner posted on X that his vehicle’s battery seal had failed after a recall was issued. Tesla insurance and Tesla Service both did not assist, and it took CEO Elon Musk stepping in to get the issue resolved:

Another owner suggested there should be a more streamlined communications process between the customer and the Service Center, a solution that has been missing.

Raj Jegannathan, a Vice President of IT/AI-Infra, Apps, Infosec, and Vehicle Service Operations, revealed that Tesla has started a small pilot program at a few service locations to combat this issue.

Jegannathan said that Tesla has started to share local and regional leader contact information so customers have the ability to reach out when they have complaints or disagree with warranty claims, changes in estimates, or initial diagnostics.

It is available in a handful of locations already, and Jegannathan said that once abuse guardrails are built, this will expand to all locations:

This would be a major improvement in the Service portion of Tesla’s business. There are common disagreements between Service and customers, specifically when Service’s suggestions don’t align with the customer’s beliefs.

When it comes to things like a warranty claim, these issues are not really up for interpretation. Instead, the repairs should be made. If there is a misunderstanding on Service’s side, a simple message from the customer could have resolved the issue. That’s basically what happened here.

Tesla gets its best analysis from Morgan Stanley as ‘it’s all about to change’

He maintained its ‘Overweight’ rating and the $410 price target Morgan Stanley had on the stock.

Tesla has gotten perhaps its best analysis from Morgan Stanley in quite some time, as the Wall Street firm claims that “it’s all about to change.”

That phrase could be used for both the company’s status and the world in general.

Analyst Adam Jonas said in a new note on Thursday to investors that Tesla could be one of the major winners in terms of the global transition from what it is now to what it will be.

He describes the global shift that will occur over the next few years:

“Have you interacted with a robot today? Have you even seen a robot today? No? Well, take a mental picture because it’s all about to change. When we meet someone who has never been in a Waymo or a Tesla Cybercab (which is most people), we frequently see a wince and a response such as ‘I’m not sure I’d feel comfortable getting in a car without a driver.’ We imagine going back in time to 1903 and asking people if they’d feel comfortable in an airplane.’”

The same technological revolutions that have occurred over the past 150 years will continue to occur again and again. We are on the verge of another, Jonas believes, as companies like Tesla are working on artificial intelligence tech, which includes changing the way we look at things like transportation and labor.

Jonas includes an interesting tidbit in his note about how humanoid robots could change wages, and how it could work into the advantage of Tesla, especially as it is developing its own Optimus robot:

“We estimate 1 humanoid robot at $5/hour can do the work of 2 humans at $25/hour, generating an NPV of approximately $200k/humanoid. 1 robot shaped car can potentially drive down cost/mile of a ride share vehicle to <$0.20 mile (1/10th human-driven ride-share).”

Jonas sees Tesla as a key player in how AI will impact things like manufacturing and various automotive industries, and he believes there is long-term potential for AI, robomobility, and even autonomous eVTOL platforms.

Tesla is expanding its Robotaxi program in Austin, Texas, as several people have received invitations to participate and take rides.

Tesla first launched the Robotaxi platform on June 22. It invited a handful of people to participate in the first-ever public rides. We were lucky enough to get an invitation, and our permissions have been expanded in the Bay Area pilot program as well.

The group was small and consisted of big names in the Tesla community. It expanded and is continuing to offer these exclusive invitations to notable members of the Tesla community.

There have been fewer than five subsequent invitations after the first group’s were sent in late June:

Tesla’s new Robotaxi geofence shape is an FU by Elon Musk to the competition

“We are being very cautious. We do not want to take any chances, so we are going to go cautiously. But the service areas and the number of vehicles in operation will increase at a hyper-exponential rate,” CEO Elon Musk said during the Q2 Earnings Call.

Eventually, the Robotaxi platform will not require an invite, and it will operate without geofences. Musk believes Tesla can get there within three or six months, and plans to have at least half of the U.S. population with access to a Robotaxi by the end of the year:

“I think we will probably have autonomous ride-hailing in probably half the population of the U.S. by the end of the year. That’s at least our goal, subject to regulatory approvals. I think we will technically be able to do it. Assuming we have regulatory approvals, it’s probably addressing half the population of the U.S. by the end of the year.”

Tesla plans to have regulatory approval in Nevada, Arizona, and Florida sooner than in other states.
