Just a quick thought on the possibilities a recent Nature article is bringing to not just a few but everyone. As written in the
New York Times, Matthew Nagle was given a neural implant that allows him to manipulate devices with his thoughts alone. This amazing work should be highly regarded. But now what? Eventually, the technology will continue to develop to the point where movement and manipulation of one's environment will be near flawless. But where will the line be drawn? People paralyzed are obviously not to be denied this treatment, but are there possible beneficial uses for those of mankind with full physical ability? It seems like science fiction, but now the manipulation of our environment is a two-step process. We think, the signal travels, our hands move, the object we want is moved. If we eliminate the hands, could we increase efficiency for some tasks? Would it be useful? I am sure that professional neuroscientists are well ahead of me with possibilities.
