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.
