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.”

That movie was so awful, even then. That and Battlefield Earth are guilty pleasures but they're truly terrible.

I feel like they belong in separate categories though. Lawnmower man was regular bad, like it started as something that had value but effects and writing just weren’t up to where they should have been resulting in a hilarious, guilty pleasure mess.

Battlefield earth never stood a chance, everything about it was cursed start to finish and was a complete vanity project by a religious weirdo. There’s just plain guilt with it, no pleasure.

Calling him a religious weirdo gives too much credit to the cult/scam that scientology is. At best he's a brainwashed cult member. I feel like 200 years from now people will be studying the rise and fall of scientology as it's a fascinating case study of what happens when a scammer sets out to create a cult and actually succeeds. The fact he got away with it despite evidence that it was always intended as a scam is even more mind blowing.

The only thing remarkable about Scientology and Mormonism are that they were recent creations. That means we have fairly decent information about the founders. The other religions probably started similar ways but that has been obscured by time and poor documentation. The more people that get involved in steering them through the years, the more blurred it gets.

Pretty much. At this point a religious weirdo is a religious weirdo no matter what flavor they prefer.

[–] [email protected] 2 points 6 months ago

I mean yeah, but it's interesting that even with all that readily available evidence of how much of a scam it is people still sign up. At the end of the day the only real difference between a cult and a religion is how old it is. But while you can give followers of other religions the benefit of the doubt because that evidence has been lost to time, it's very much still available for scientology. Hence calling him a religious weirdo is too much credit, followers of scientology have ample evidence that it's a scam/cult, but they choose to ignore that evidence. There's basically no excuse for believing in scientology much like there's no excuse for believing the Earth is flat.

6 of one, half a dozen of the other.

Come on, the CGI was groundbreaking.

Tron has entered the chat

[–] [email protected] 6 points 6 months ago (2 children)

If I recall, Tron was almost entirely practical effects despite its premise.

15 minutes of CGI-only scenes, but ok. Last Starfighter then.

[–] [email protected] 6 points 6 months ago

I thought The Last Starfighter was shot on location.

Honestly the fact it had any CGI was groundbreaking. We take it for granted these days how easy CGI is, but at the time Tron was made movies were still recorded on physical film and most computer monitors were 480P resolution at best. The movies in the 70s and 80s that had "digital" displays like the terrain map in Aliens used some really clever tricks to fake things that would be utterly trivial to do today but were almost impractical to do back then.
