Noland, himself, just said on the HardFork podcast 2 days ago that they are not detached. They shifted, and after a software upgrade and no follow-up surgery, they are working better than ever. There was a short period of time between when they shifted and the new software update that he had reduced control of his mouse.
Edit:
This is such a garbage journalist. They say that Noland said they detached in a WSJ article, and then they link an article that says nothing about this. I don't know if this is the same Popular Science that used to put out good journalism, but if so, then they really dropped the ball with joirnalist. I get that Elon has done some shitty stuff, but it does nobody any good to just blatantly lie about this. It is easily checked. Think twice before posting stuff from Popular Science.
OP, for the sake of the reputation of this community, you may want to adjust the post title with a misleading warning or something.
An estimated 85-percent of Neuralink’s brain-computer interface (BCI) implant threads connected to the first human patient’s motor cortex are now completely detached and his brain has shifted inside his skull up to three times what the company expected, volunteer Noland Arbaugh told The Wall Street Journal on Monday.
You don't address this claim from the article. You just say they've compensated with software. The fact still seems to be, at least to me based on what I am reading, that the wires have detached and shifted from their intended locations regardless of what effects that has had.
The guy with the chip in his head talks about this exact thing in the podcast I linked. He said that they did not detach, they just shifted locations. For a little while, his brain mouse was less responsive, but after the update, it is now better than it ever was. He said a lot more, but I don't remember everything. It was really interesting listening to him talk about it. It is nothing like how the article makes it sound. There are no little detached wires floating around inside his brain or anything.
I recommend listening to his interview, it is maybe halfway through the episode if you want to skip ahead. He is absolutely thrilled with the experience so far and said he was absolutely willing to go back in for surgery, but there was no need to.
The article says, "Arbaugh said that Neuralink has told him around 15% of the threads inserted in his brain remain in place." Then says that they did software updates to strengthen the remainder.
Neuralink themselves used the word "detached" "retracted" in their blog.
