I don't think the concept is bad. I take a medicine that may give me cognition problems when I'm very old, but it's remarkably effective for me right now and provides a significant quality of life improvement. So, I've chosen to stay on it.
That's different I think though from Neuralink as it is today. There need to be stringent safety measures in place and controls on testing. We've come a long way on neurology, but we still have a lot we don't understand.
