As Brain-Computer Interfaces Advance, Scientists Warn of a New Threat to Human Privacy

The United Nations has issued a warning about the potential misuse of neurotechnology, calling for limits on the rapidly advancing field amid concerns over how it might potentially impact individual privacy and freedoms. 

In the Secretary-General’s report to the General Assembly, senior human rights official Claudia Fuentes Julio argued that brain-computer interfaces (BCIs) and other related neurotechnology could threaten freedoms of thought, privacy, and the right to a fair trial, which could in turn target marginalized communities globally. 

“Neurotechnology accesses, measures and analyses brain signals,” António Guterres, Secretary-General of the United Nations, wrote in his report. “If these signals are treated as direct indicators of thoughts, intentions or truthfulness, the use of neural data points could undermine how we understand and value each of us as human beings.” 

Currently, regulations governing brain-computer interfaces (BCIs) in the United States and many other countries are largely focused on medical applications. For instance, as of October 2026, Neuralink’s implanted brain-computer interface is subject to the FDA’s medical-device regulations, including requirements governing investigational devices and human clinical trials.

However, the consumer neurotechnology sector is expanding rapidly, and BCIs may soon become increasingly familiar consumer products. Originally, noninvasive consumer BCIs were primarily associated with gaming, but companies developing technologies such as Sabi, the BCI beanie, and AlterEgo are exploring applications that extend into everyday life.

These technologies aim to enable new forms of hands-free interaction, from converting intentionally generated mental commands into computer inputs to communicating with AI systems without conventional speech or typing. Some approaches use brain signals, while others rely on different physiological signals associated with attempted or silent speech, eliminating the need for surgically implanted devices.

While remarkable, some experts warn that such technologies can lead humanity down a slippery slope. 

Reading One’s Thoughts to Incriminate Themselves 

United Nations Secretary-General António Guterres warned that, “Neurotechnology, including new and emerging forms, raises profound human rights challenges when applied to the administration of justice. Its expansion beyond clinical settings into investigative, judicial, and correctional contexts introduces significant risks, alongside potential benefits.”

The prospect evokes the premise of the popular Tom Cruise film Minority Report, in which authorities attempt to prevent crimes before they occur. Although current neurotechnology cannot reliably predict future criminal behavior, its potential use to extract or interpret information from suspects’ neural activity raises significant legal and ethical questions.

As the  New York Times reports, police in India have used a controversial technology known as Brain Electrical Oscillation Signature (BEOS) profiling over the past two decades to assess whether suspects may possess knowledge associated with a crime.

The technique analyzes patterns of electrical brain activity in response to stimuli and has reportedly been used in investigations involving murder and sexual assault. However, its scientific reliability and use as evidence have faced serious challenges, including legal restrictions in India.

The Mind ACT

On September 24, 2025, U.S. lawmakers introduced the proposed Management of Individuals’ Neural Data Act of 2025 (MIND Act), seeking to strengthen protections for neural data.

The proposed legislation calls for federal agencies, including the Office of Science and Technology Policy (OSTP) and the Office of Management and Budget (OMB), to develop guidelines and a framework addressing the ethical, safety, and privacy implications of neurotechnology. Its goal is to identify regulatory gaps and ensure that individuals are adequately protected under U.S. law as these technologies advance.

Although the MIND Act has not advanced into federal law, individual states have begun taking action. Colorado, California, and Montana have enacted measures addressing the protection of neural data, while countries across Latin America, including Brazil, Mexico, Colombia, Argentina, and Chile, have explored or pursued various forms of neurotechnology regulation.

In an email exchange with The Debrief in October 2025, Kurt Haggstrom, Chief Commercial Officer at Synchron, a company founded by CEO Tom Oxley, said, “responsible oversight builds the public trust that medical innovation depends on—and that’s essential for bringing BCIs safely into healthcare systems.

“Our CEO, Dr. Tom Oxley, serves on the World Economic Forum’s Neurotechnology Governance Committee, where he’s helping shape the global dialogue on how to advance these technologies safely, ethically, and inclusively,” he added.

Elon Musk and The Neuro Elite

Several companies are leading advances in neurotechnology that could eventually transform how people interact with computers and digital systems.

Elon Musk’s Neuralink is among the companies highlighted in an October 8 Morgan Stanley report titled Neuralink: AI in your brAIn. The report examines Neuralink’s position within an emerging technological sector with potentially far-reaching implications for healthcare, gaming, defense, investment, and society.

It also raises the possibility that medical applications could provide a pathway toward a broader consumer market for brain-computer interfaces.

Such developments have prompted concerns about the emergence of a potential “neuro-elite,” in which wealthy individuals gain access to advanced neural implants and cognitive-enhancement technologies that remain unaffordable or inaccessible to much of the population. If such capabilities become available, unequal access could deepen existing social and economic disparities.

CHINA and BCI Escalation 

Since 2010, China has increasingly prioritized brain-computer interface development, positioning itself as a major international contender in the emerging industry.

In March 2026, China became the first country to approve an invasive BCI for commercial use. The device, known as NEO, was developed by Shanghai-based Neuracle Medical Technology and is designed to help patients with paralysis caused by cervical spinal cord injuries regain the ability to grasp objects.

The approval applies to the Chinese market and does not constitute authorization for the device’s sale or medical use in other countries.

The United Nations has also addressed the potential risks associated with neurotechnology, proposing recommendations that include internationally coordinated regulations, treating information derived from brain activity as highly sensitive personal data, and requiring explicit consent before neurotechnology is used in criminal justice settings.

As BCIs become increasingly relevant to healthcare, law enforcement, and consumer technology, concerns are growing over neural privacy, unequal access, and the possibility that technological advances could outpace existing legal protections.

With human rights organizations and researchers calling for stronger oversight, a larger question remains: Is it time for countries around the world to establish a global coalition to protect neural privacy and individual autonomy before these technologies become even more deeply integrated into everyday life?
