Elon Musk’s Neuralink, a brain-computer interface (BCI) company, has ignited a firestorm of controversy with its recent announcement of a successful human implant. While this marks a significant step in BCI technology, ethical concerns regarding animal testing practices cast a long shadow over this achievement.
A Promising Step, Mired in Controversy:
Musk, known for his bold pronouncements, declared the unidentified human subject to be “recovering well” with “promising neuron spike detection.” However, the lack of independent verification and the troubling history of animal testing raise serious questions about the ethics and transparency surrounding this development.
A Trail of Troubled Primates:
Neuralink’s animal testing has been marred by disturbing reports of suffering and death in macaques. Investigations revealed incidents of brain swelling, self-harm, and infections, leading to euthanasia in several cases. The company allegedly failed to disclose these details to investors, sparking potential legal troubles with the SEC.
Amid those announcements, however, were some jarring and grotesque reports about the fates that befell some of the company’s animal test subjects.
In a September report that dropped just a day after Neuralink announced that it was recruiting for its human trials, Wired reported that as many as a dozen of the rhesus macaques the company experimented upon suffered all manner of freakish symptoms, including brain swelling, partial paralysis, and self-harming behavior. Eventually, many of the monkeys had to be put down.
In one 2019 incident, a chip that was being implanted into one of the macaques’s brains “broke off” during the procedure. After the monkey woke up from its botched surgery, it scratched at the site of the implant, made itself bleed, and partially dislodged it. The wound, as it turned out, was infected, but because the implant blocked any treatment options, the macaque was euthanized.
Another 2019 experiment subject was witnessed pressing her head to the ground following implantation and picking at her surgery wound until it bled, eventually losing her coordination. She too was euthanized.

All told, some 21 percent of the company’s monkeys reportedly died because of brain implant issues.
Regulatory Scrutiny and Ethical Questions:
While the Department of Agriculture closed its investigation without major findings, the Animal Welfare Act remains a point of contention. The high mortality rate among test subjects and alleged lack of transparency raise ethical concerns that cannot be easily dismissed.
The Human Factor: Balancing Risk and Reward:
The decision to move to human trials, despite the checkered past, highlights the complex trade-offs inherent in scientific advancement. Balancing the potential benefits of BCI technology with the risks to human subjects requires careful consideration and ethical rigor.
Moving Forward: Transparency and Accountability:
As Neuralink progresses with its human trials, transparency and accountability are paramount. Independent verification of results, open communication about potential risks and benefits, and adherence to the highest ethical standards are crucial to gaining public trust and ensuring responsible development of this groundbreaking technology.
