Oh well – next!

The first human to get a Neuralink implant may be doing fine now, but that's after a good deal of work to address post-surgical trouble that saw its performance significantly degrade."In the weeks following the surgery, a number of threads retracted from the brain, resulting in a net decrease in the number of effective electrodes. This led to a reduction in BPS ," Neuralink said in the post.

"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Neuralink said in its post."These refinements produced a rapid and sustained improvement in BPS, that has now superseded Noland's initial performance.

Pneumocephalus is often asymptomatic and harmless, as is apparently the case for Arbaugh, but that reportedly didn't stop Neuralink from considering removing his implant entirely when threads begin to slip.
