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.

    I understand that paralyzed people are desperate to be able to move again, or at least control things that will move for them, but trusting Neuralink to do it right just seemed like a bad plan the first time they announced human trials. Just don’t do it. The initial patient is lucky they’re not dead.

      Implanted human brain-computer interfaces have been around since the 70s. And nowadays Parkinson’s patients routinely get stimulating electrodes implanted in far deeper (ie riskier) brain structures than Neuralink’s surface electrodes.

      While I certainly don’t buy Musk’s hype regarding this technology, I also see no reason to believe that Neuralink will be significantly more dangerous than what we already have.

        The warning signs were there. You should read about their animal trials. If you have a strong stomach.

        I don’t see how. They aren’t blaming the victim for anything. Just noting the desperation overtaking logic isn’t a good thing around ol Musk.

        It’s not victim blaming, it’s calling out Musk for taking advantage of vulnerable people. There is a rigorous (and expensive) process to testing new medical devices because of the potential to do serious harm . Musk is trying to save time and money by yeating a product he knows is flawed on people desperate to change their circumstances.
