It's already old news. A very good friend of mine since university days came down with Parkinson's Disease, which rapidly began to dominate his motor control. He ultimately had two cerebral implants to modulate the tremors to his hands and arms. It didn't entirely stop the Parkinson's however; his speech was very difficult toward the end. He passed away recently---of pneumonia, but weakened by the Parkinson's.

I worked in the prosthetics business back in the 1970s doing optical engineering for intraocular lenses. That technology began shortly after World War II. It has been a boon to many people who suffered cataracts.

You can "mix" your feelings all you want, but that is only technology paranoia. Technology can do good and wonderful things for us. It can also be misused in hideous ways. Don't confuse the artist's equipment with the paintings painted.
