Here is the engineering nightmare. Most neurotech uses systems: the chip records, the computer processes, the chip stimulates. To deactivate safely, you need a closed-loop system that ramps down stimulation as the brain compensates.

Whether it is the intentional "turning off" of a medical implant, the accidental failure of a brain-computer interface (BCI), or the ethical debate surrounding the permanent removal of neural enhancements, deactivation is as complex as the technology itself. 1.
