Exclusive: Musk's Neuralink has faced issues with its tiny wires for years, sources say (www.reuters.com)

Neuralink's disclosure last week that tiny wires inside the brain of its first patient had pulled out of position is an issue the Elon Musk company has known about for years, according to five people familiar with the matter.

The company knew from animal testing it had conducted ahead of its U.S. approval last year that the wires might retract, removing with them the sensitive electrodes that decode brain signals, three of the sources said. Neuralink deemed the risk low enough for a redesign not to be merited, the sources added.

The company said last week that the implant's tiny wires, which are thinner than a human hair, retracted from a patient's brain in its first human trial, resulting in fewer electrodes that could measure brain signals.

Also the timeline that's expected to happen on. I'd be pretty fucking mad if my phone had dead pixels less than 6 months after buying it. 10 years, not so much.

Likewise, I'd be pretty mad that if a reportable amount of my brain electrodes detached within the first 6 months of having them, but I'd be less mad if it was a few years down the line (not that I'd ever be fully okay with it. This is my brain, after all).

That's because screens are a mature technology. Twenty years ago, you expected one or two dead pixels in every brand new screen.

Here's an example of a replacement policy from those dark ages:

The LCD display of products under warranty will be replaced if CTL determines that it has 6 or more bright sub-pixels, 6 or more dark sub-pixels or a combination of 6 or more bright and dark sub pixels.

It's a lot easier to warranty a phone screen than it is brain surgery. That's why that expectation was acceptable for screens.

By the same token, medical devices have more built-in redundancies in case of partial failure. That's why the overall impact on the patient is more important than how many electrodes are operational.

I will admit, I think I'm coming from a place of zero trust that anything musk has his hands in has any amount of safety or redundancy built in, because that might hurt the bottom line

[–] [email protected] 1 points 6 months ago

Pretty much every medical device is made by people who are equally interested in the bottom line, they just aren't constantly in the media spotlight like Musk.

Fortunately there are government agencies that closely watch these companies to make sure patient safety comes first.
