First human brain implant malfunctioned, Neuralink says (thehill.com)

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.”

Yeah I feel like it’s an attempt to resolve the Deaf stance that deafness isn’t a disability. The general stance of the Deaf community is closer to that of the queer community than that of say the paraplegic community. It sees deafness as a disability constructed by a society unwilling to communicate visually and to teach signed languages to all people able to use them.

Mind you we’re the contentious portion of the disabled world. The Deaf are as bad as lesbians I tell ya.

But on point, “differently abled” feels like it washes away the struggle. I am disabled. I’m disabled by a society that taught my great grandparents, my grandparents, and my parents not to teach their hard of hearing children sign language because otherwise we won’t use English. I’m disabled by a society that doesn’t include visual signals in emergency sounds even when it’s easy to do. I’m disabled by a society where people, including cops, will speak to the back of my head and not even consider that I didn’t respond because I didn’t hear. And I’m disabled by the assumption my life has to be worse for having less sound as though I’m not extremely literate and completely capable of using a signed language. I’m not “differently abled” I’m completely able in most ways everyone else is, and people who can’t learn to communicate visually are just as disabled as people who can’t learn to communicate audibly.

I know this is a point of some contention among the deaf community, but how do you feel about the development of a "standard" international sign? Personally, and I'm speaking as a fully hearing person, I think a basic international sign should be developed and taught to everyone. Not only to facilitate communication with the hard of hearing, but also in loud environments and with those who don't share a spoken language.

It's my understanding that a large portion of the deaf community is hostile to the idea of a universal sign from a cultural perspective, since each regional sign has cultural content. However I think it's a potential solution for numerous issues, with more pros than cons.

You misunderstand language itself, not just sign language, if you think a universal language is possible or even a good thing
