"The Augmented Human"

An article on the future of bioengineering is both fascinating and just a little creepy. It features some of the more-than-human abilities our cyborg grandchildren will enjoy.
Among the highlights:

• An implanted microchip in the brain will allow a person to send brain signals and control machines.
• Contact lenses that will monitor blood pressure and blood sugar.
• A wireless transmitter implanted in a tooth that will act as both speaker and microphone for a cellphone by sending soundwaves to the eardrum.
• A prescription dispenser—implanted in the chest—that monitors body chemistry and releases drugs into your body when you need them.
• Implants that will rejuvenate paralyzed muscles, damaged brain tissue and hearing nerves in the ear.

Now, this all sounds promising, but anyone who's ever read a science-fiction novel has to be a little uneasy.
