I'm actually super optimistic about the future and the thought of having a microchip in my brain doesn't scare me at all. Other people's concerns are definitely valid (there's some fucked up stuff you could do to someone once you would have control over their brain) but if it will cure stuttering, I'm getting it 100%, wouldn't hesitate for a second. Safety is people's number one concern and Neuralink knows that, so to be even able to sell their product, they will have to prove that it is completely safe, removable etc.
