# Neuralink Employees Admit Company Has Killed 1,500 Animals So Far

We already knew that there were problems at Elon Musk's brain-computer interface startup, Neuralink. Internally, employees have [warned of chaos](<https://futurism.com/the-byte/elon-musk-neuralink-disaster>) as they say Musk pushes for overly ambitious goals. Externally, [subject matter experts say](<https://futurism.com/neuralink-demo-impress-experts>) that Musk's glib promises gloss over profound challenges standing in the way of a commercial brain implant for humans — and [downplays deep ethical questions](<https://futurism.com/neoscope/scientists-horror-elon-musks-neuralink>) that will emerge if it does succeed.

Another problem has been looming since early on as well: criticism of how the venture is treating its animal test subjects. Now, a [bombshell *Reuters* story](<https://www.reuters.com/article/idUSKBN2SP1W7>) reports that those concerns have deepened considerably in the form of a federal probe about animal wellbeing at the company by the US Department of Agriculture’s Inspector General, at the request of a federal prosecutor.

*Reuters*' reporting sounds extensive, drawing on what the news agency says are interviews with numerous current and former employees of Neuralink at a "time of growing employee dissent about Neuralink’s animal testing."

The specific allegations are grim, with *Reuters* reporting that Neuralink has since 2018 so far killed around 1,500 animals, including 280 sheep, pigs and monkeys. It's not clear how many of the animals have died specifically after being implanted with the company's prototype brain chip — which Musk [said this week](<https://futurism.com/neoscope/elon-musk-monkey-type-brain-implant>) expects to be implanting in human subjects within six months — but it had been [previously reported](<https://futurism.com/neoscope/neuralink-brain-chip-monkeys>) that 21 percent of its monkeys died because of issues with the devices.

Sources tell *Reuters* that many mistakes endangering animal wellbeing are avoidable. For example, employees told the outlet, the company allegedly botched surgery on two pigs when it implanted their chips on the wrong vertebra, leading the company veterinarian to recommend killing one of the animals due to its "poor psychological well-being."

Worse, employees told *Reuters* that mistakes that led to the animals' deaths were sometimes exacerbated by Musk pushing the company to work faster than was safe. One employee vented to colleagues in a message obtained by *Reuters* that the company's work on animals was a "hack jobs." The outlet reported that numerous employees have raised the concerns internally, and some have left the company entirely due to concerns about how the animals were being treated.

Another detail reported in the story smacked of an ugly retroactive approach to scientific literature: after Musk described the company's approach to surgery as "confirmatory, not exploratory," company researchers were allegedly instructed to scrub the word "exploratory" from study titles retroactively, and to avoid using it in the future.

Neuralink's problems with perception of its animal testing had been building for some time. PETA has [spoken out the company](<https://futurism.com/peta-upset-elon-musk-testing-neuralink-pigs>), and a [legal battle is currently underway](<https://futurism.com/uc-davis-neuralink-monkey-photos-lawsuit>) to obtain photos of monkeys that Neuralink experimented on at the University of California, Davis.

A federal investigation, though — as well as what sounds like growing rancor at the company over Musk's dictatorial managerial style — could represent a swiftly darkening shadow over the company already-challenged venture. The drama also comes as Musk is facing [steep challenges](<https://futurism.com/the-byte/twitter-fired-employees-come-back>) at his just-acquired social media site Twitter as well as [delays at SpaceX](<https://www.cnbc.com/2022/11/11/spacex-shakes-up-starbase-leadership-in-starship-push.html>) and a [range of problems at Tesla](<https://www.foxbusiness.com/markets/tesla-shares-sink-amid-china-production-slowdown-rumors>).

## Author
I'm responsible for editing, assigning, and scouting at Futurism, as well as occasionally writing for the site. That work involves keeping an eye on a wide range of narratives and issues, but over the past few years I've become increasingly interested in how AI is shaping the future of media, the web, and information itself. My day-to-day often involves collaborating on reporting and commentary projects bylined by my colleagues, but I try to find time to do my own reporting as well; stories I've broken for Futurism have been cited by publications including the New York Times, the Washington Post, the New Yorker, Wired, Ars Technica, New York Magazine, the Columbia Journalism Review, Bloomberg, and more. I grew up in Southern Vermont and attended Vanderbilt University. Prior to Futurism, I contributed to outlets including the Boston Globe, Vice, Wired, Slate, the Atlantic, the Outline, Ars Technica and more, and did stints in farming and food service. I currently live in Brooklyn, New York, and in my free time I enjoy pinball, word games, cycling, running, and music production.
