At CES 2025, Elon Musk provided a major update on the progress of Neuralink, his brain-computer interface (BCI) company. During a live-streamed interview with Stagwell CEO Mark Penn, Musk revealed that Neuralink had successfully implanted its device in a third human patient, signaling significant advancements in the technology. The billionaire entrepreneur also shared plans to expand the number of human trials in the coming year, with the company aiming for 20 to 30 additional procedures in 2025.
Neuralink’s Growing Human Implant Trials
Musk began by discussing the company’s progress in human trials, noting that the device, which is designed to interface directly with the brain, has been successfully implanted in three patients. The upgrades to the Neuralink devices include more electrodes, enhanced bandwidth, and longer battery life. According to Musk, these improvements will make the devices more effective and enable even more groundbreaking results. The company is now looking to expand its human trials, planning for the implantation of up to 30 new devices over the course of the year.
The Immediate Goal: Restoring Communication for the Disabled
One of the core goals of Neuralink’s technology is to help those who have lost their brain-body connection due to neurological conditions. Musk emphasized that the initial focus is on assisting individuals who are tetraplegic, paraplegic, or those suffering from conditions such as ALS, including the late Stephen Hawking. The technology is designed to read the motor cortex of the brain, enabling users to control digital devices simply by thinking. In practice, this means that people could potentially use a computer or smartphone more efficiently, bypassing the need for physical movement.
Future Aspirations: Enhancing Vision and Mobility
Beyond communication, Musk shared Neuralink’s plans for further expanding its capabilities. One of the company’s next major goals is to develop a “Blindsight” device, which could restore vision to individuals who have lost their eyes or optic nerve. Neuralink has already demonstrated success with this technology in monkeys, and Musk expressed optimism about the future potential to restore sight in humans.
Additionally, Musk discussed the possibility of helping individuals with spinal cord injuries regain mobility. By implanting a second Neuralink device beyond the point of spinal damage, the company believes it can transmit signals from the brain to the body, essentially bypassing the broken neural pathways. Musk is confident that this type of brain-spinal interface will be physically feasible and could lead to significant improvements in the quality of life for individuals with paralysis.
Long-Term Vision: Expanding Human Brainbandwidth
Looking ahead, Musk also outlined Neuralink’s long-term goal of increasing the bandwidth of human brain activity. As he explained, the current data transmission rate of the human brain is extremely low, with the average human communicating less than one bit per second over 24 hours. The ultimate ambition for Neuralink is to enhance this bandwidth, facilitating faster and more efficient communication between the brain and digital devices. This improvement could radically transform how humans interact with technology, allowing for seamless integration between the brain and the digital world.
Neuralink’s Ambitious Path Forward
With these advancements, Neuralink continues to push the boundaries of what’s possible in brain-computer interfacing. As the company progresses toward helping those with severe disabilities, Musk’s vision of restoring lost capabilities—whether through communication, mobility, or vision—holds the potential to change the lives of millions. The upcoming year’s trials will be a critical step in realizing these ambitious goals, as Neuralink strives to build the future of human-technology integration.
