As our computing power grows bigger and our iPods get smaller, the question of cybernetic implants becomes more a reality. Though some still dismiss it as science fiction, scientists have already made the blind see, the deaf hear, and the paralyzed type and move cursors, all through a brain-machine interface. So it’s only a matter of time before entire portions of the brain can be enhanced/replaced by implants.
We see commercials for Red Bull and FocusFactor, promoting concentration and awareness, but that’s just the tip of the iceberg. The prescription of cerebral enhancers like Adderall and Ritalin is growing every year, with a significant portion of the drugs overflowing into the black market. As this trend continues, people without learning disabilities might be forced to take cerebral enhancers just to compete in their school/work environment (this argument echoes the movie Gattacca). That, or we have a whole generation hopped up on goof balls.
Later, as cybernetic brain implants develop, at first to battle things like Alzheimer’s - only to spread into the general market, people will have to choose again, enhance or fall behind (evolve or perish, if you’re extremist). Some think this won’t happen for a while, but as soon as the technology arrives, there’ll be someone who’s willing to put it inside them. We already have plenty of unneccesary surgery: nose jobs, breast implants, hair grafts. If you’re going to put silicone in your breasts, why not silicon in your head?
All this raises a curious question in the philosophy of mind, one that echoes a riddle from the classics. If you have a ship and, as parts of it break, you replace them to the point that none of the original parts remain, is it still the same ship? (Further, if someone takes the discarded parts and reassembles them into another ship, which one is the original?) Now apply this to the brain. If you replace it bit by bit until it’s all cybernetic, is it still you? Those who don’t believe that a machine can be conscious will say no, but then what happens to you as you replace those parts? Does your consciousness fade gradually? Is there a specific point when you go from man to machine and your self-awareness vanishes? Perhaps soon we’ll find out.
