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

Published

on

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.

A curious soul who keeps wondering how Elon Musk, Tesla, electric cars, and clean energy technologies will shape the future, or do we really need to escape to Mars.

16:38 CT – With Tesla achieving clarity on Unsupervised FSD, Musk stated that he feels “confident in expanding Tesla’s production.” He also noted that Tesla Energy is rising quickly, especially with products like the Powerwall and the Megapack. “We see the potential there for Tesla battery packs to improve the energy output per year of any given grid, the US or otherwise.”

16:40 CT – Elon also reiterated his prediction that Tesla Optimus could be the largest product in the world. A good reason for this is the fact that Tesla has scale, Musk stated. Musk also stated that it’s easy for users in the United States to test out FSD V14 for themselves. He also mentioned that Tesla is currently hard at work with Megapack 4.

“We look forward to unveiling Optimus V3 in Q1. I think it will be quite remarkable,” Musk said, adding that V3 will almost seem like a person in a robot suit.

16:45 CT – Musk summed up his opening remarks with a comment on Tesla’s updated mission.

“In conclusion, we’re excited about the updated mission of Tesla, which is sustainable abundance. We’re going beyond sustainable energy. We believe that with Optimus and self-driving, we can actually create a world where there is no poverty, where everyone has access to the finest medical care.

“Optimus will be an incredible surgeon. Imagine if everyone had access to an incredible surgeon. I think we’re headed to sustainable abundance, and I’m excited to work with the Tesla team to make that happen,” Musk said, summing up.

16:48 CT – Tesla CFO Vaibhav Taneja discussed the company’s rollout of its expanded Model Y lineup such as the Model Y L, as well as the advantages of the Robotaxi network. He also confirmed that Tesla is looking to secure approvals for FSD tests in several areas across the globe.

He also discussed Tesla’s regulatory credits. “”While regulatory credits declined sequentially, we entered into new contracts and delivered on previous contracts,” he said.

16:54 CT – Investor questions are asked about demand for Megapack and Powerwall. Tesla noted that Tesla is seeing a lot of interest and demand for Megapack and its related products. There is also a surge in demand for residential batteries.

Looks like the Tesla Solar Roof is coming alive as well.

16:59 CT – A question about the challenges of Optimus’ rollout was asked. Elon Musk noted that bringing Optimus to market would not be a walk in the park. It will be a very difficult endeavor. “It’s an incredibly difficult thing,” Musk said, adding that the hands of Optimus are very difficult to design and produce due to its complexity.

Tesla is really putting a ton of work on Optimus’ hands, likely because the robot will need to be very dexterous to be useful in both residential and industrial applications. He noted that for Optimus to be successful, Tesla must really be vertically integrated.

Elon also mentioned that Optimus is one of the reasons behind his goals with his 2025 compensation plan. He needs control of Tesla if the company is building a literal robot army.

17:05 CT – A question about Tesla’s chip deal with Samsung. Elon noted that he has nothing but good things to say about Samsung. He then clarified that Tesla will be focusing both TSMC and Samsung on AI5.

“The AI5 chip design by Tesla is an amazing design. I have spent every weekend for the last few months with the chip design team working with AI5,” Musk said. “By some metrics, the AI5 chip will be 40x better than the AI4 chip.” This is because the hardware is designed for Tesla’s software stack.

There is also a lot of efficiencies and deletions that have been implemented on AI5. “This is a beautiful chip,” Musk said, reiterating that both Samsung and TSMC will be producing AI5. Tesla wants an oversupply of AI5 chips. If there’s an oversupply, Musk said that the chips could just be used for training in Tesla’s data center.

17:09 CT – A question was asked about Tesla abandoning HW3 was asked. The CFO stated that Tesla is not abandoning HW3. “We will definitely take care of you guys,” he said, adding that he himself is driving a HW3 car. Tesla executives also noted that the company is developing a V14 “Lite” for HW3 cars.

17:13 CT – A question about the Tesla Semi’s autonomy was asked. Tesla noted that things are progressing with the Semi program. Analyst questions now begin. First up is Wolfe Research, which asked about Elon’s comment about Tesla now focusing on volume with FSD now developed.

Elon Musk responded that Tesla’s capacity today is not at 3 million cars yet, but Tesla can probably achieve that level in 24 months or less. “We’re gonna expand production as fast as we can, and as fast as our suppliers can keep up with it,” he said.

He added that the Cybercab will be a big project since it’s a your de force of engineering optimization due to its driverless nature. He also stated that Cybercab production will start in Q2 2026.

17:21 CT – Barclays asked about markets that are outside of Tesla’s core competencies. Elon noted that Tesla had zero core competency when it started. He highlighted that Tesla today is still a bunch of startups that are working together. He did also state that “Optimus at scale is an infinite money glitch” since it could 5X a person’s productivity.

17:27 CT – Lightshed asks about the Robotaxi program and the removal of safety drivers in Austin by year end. Musk noted that Tesla will be very cautious with FSD’s rollout. He noted that Tesla will be paranoid about safety. He noted that Tesla typically rolls out its FSD updates with safety at the forefront, so first builds of a major release tend to be safe but not as smooth.

“This car will feel like a living creature,” Musk reiterated, adding that Teslas will eventually be able to find parking spots on their own intelligently.

17:34 CT – Oppenheimer asked about the timeline of Optimus production. Musk noted that the hardware design of Optimus will not be frozen even after the humanoid robot starts its production. “We’ll have a production-intent prototype ready to show in Q1,” Musk said, adding that hopefully, Optimus will enter production late next year.

17:37 CT – Questions for this earnings call are done, and in closing, the CFO urged shareholders to vote on the Board’s recommendations. Tesla’s future depends on it.

Tesla’s new Safety Report for Q3 shows Autopilot technology contributed to accident frequency that was nine times lower than the national average.

Tesla released its Vehicle Safety Report for Q3 2025, and it showed that one crash was recorded every 6.36 million miles drive in which drivers were using Autopilot technology.

This is a stark contrast from the most recent data made available by the National Highway Traffic Safety Administration (NHTSA) and Federal Highway Administration (FHWA), which shows there is an automobile crash approximately every 702,000 miles.

The figure for Q3 2025 is slightly lower than the one that Tesla released in Q3 2024, which eclipsed 7 million miles between accidents for drivers using Autopilot technology.

Over the past seven quarters, Q1 has been Tesla’s strongest showing with the Vehicle Safety Report, with Q4 being the weakest. This is usually attributed to weather and driving conditions deteriorating toward the end of the year.

Q1 2024 was Tesla’s best performance so far, with one crash every 7.63 million miles.

Tesla releases Vehicle Safety Report for Q1 2024

Autopilot and Full Self-Driving have been a major focus of Tesla over the past few years, and recent versions have improved on what has already proven to be an extremely safe way to travel, as long as it is used correctly.

Tesla’s Full Self-Driving (Supervised) suite is a suitable way to allow the vehicle to navigate through any traffic setting and has been widely effective for day-to-day travel. With the data Tesla gets from its use across its vehicle fleet, it gets more refined and more accurate with every passing mile.

The company has teased the potential for completely unsupervised Full Self-Driving releases in the future, but Tesla has to solve autonomy before it can offer anything like that to the public.
