Eh, I think the Neuralink electrode retraction issue was a bit overblown. It sounds as though they were able to restore functionality to the shifted electrodes via a software update:

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 (Fig 04). In response to this change, 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. These refinements produced a rapid and sustained improvement in BPS, that has now superseded Noland’s initial performance.

I think I’d still be more inclined to trust a device approved by the U.S. FDA over China’s NMPA.
