Cyborgs etc

Cyborgs are not new. People always want to create machines into their lives, even at the time they didn't have that technology. At the primate time, when people making their stone tools, they already dream about the cyborgs. Now we have all kinds of machines that involve into our lives, some of them can enhance our abilities like hearing aids or cell phones, some of them just for entertaining. Enclyopedia is a system of recording human knowledge in a limited sense. Enclyopedia is expending while the watch is repeating the cycle. I think the watch and enclyopedia are valid analogy in its own sense, because the watch is recording repetitive which can be link to the routine life. Encycopedia on the other hand, expending its data collection, as like goes day by day. What a bad design? What is a "friendly design"? Even it is an "unfriendly" design, many machines still in fact a part of us unseperatable.
The interesting question we talked in the class was "Is tatoo or earrings cyborgs?" If they are, the fashion cloth is also cyborgs. Is the definition too broad?
