The first Neuralink implant in a human malfunctioned after several threads recording neural activity retracted from the brain, the Elon Musk-owned startup revealed Wednesday.

The threads retracted in the weeks following the surgery in late January that placed the Neuralink hardware in 29-year-old Noland Arbaugh’s brain, the company said in a blog post.

This reduced the number of effective electrodes and the ability of Arbaugh, a quadriplegic, to control a computer cursor with his brain.

“In response to this change, we modified the recording algorithm to be more sensitive to neural population signals, improved the techniques to translate these signals into cursor movements, and enhanced the user interface,” Neuralink said in the blog post.

The company said the adjustments resulted in a “rapid and sustained improvement” in bits-per-second, a measure of speed and accuracy of cursor control, surpassing Arbaugh’s initial performance.

While the problem doesn’t appear to pose a risk to Arbaugh’s safety, Neuralink reportedly floated the idea of removing his implant, according to The Wall Street Journal.

The company has also told the Food and Drug Administration that it believes it has a solution for the issue that occurred with Arbaugh’s implant, the Journal reported.

The implant was placed just more than 100 days ago. In the blog post, the company touted Arbaugh’s ability to play online computer games, browse the internet, livestream and use other applications “all by controlling a cursor with his mind.”

This is more than enough to turn me off from the idea of neural anything in the brains of humans. Especially if it's all being ran by a fledgling sycophant like Musk.

Even if it's not drastic, I don't want to know what the worst case scenario would've been.

Idk... I don't like Elon, but this is actually incredibly huge overall. he controlled a computer with his mind. That's amazing for people who could benefit from it. I think it's worth continuing down this path, just to see how it evolves. I'm sure the man knew the risks and still chose to do it, meaning it was worth it to him.

This isn't something new to nueralink. Brain-machine interfaces have existed for quite some time. Neuralink is one of a number of companies that are exploring directly implanting these devices rather than using an externally attached (hence, easily removable) interface, but the core thesis of "Brain control computer" isn't any kind of grand leap forward. That's just Musk's marketing.

Especially if the extent of it is that it lets you move a mouse. How does that offer any improvement over eye tracking adaptive tech?
