Nanotechnology: Immortality


And until these questions are answered, nanotech .
             is regarded as silly (Stix 98). .
             But the nanotech optimists are still out there. They contend that the progress made by a team at .
             IBM who was able to write letters and draw pictures atom by atom actually began the birth of nanotech .
             (Darling 49). These same people answer the scientific questions by replying that a breakthrough is not .
             needed, rather the science gained must be applied (DuCharme 33). In fact, Drexler argues that the .
             machines exist, trends are simply working on building better ones ("Unbounding" 24). Drexler continues .
             by stating that the machines he spoke about in "Engines of Creation" published in 1986 should be .
             developed early in the 21st century ("Unbounding" 116). .
             However many scientists still argue that because nanotech has produced absolutely nothing .
             physical, it should be regarded as science fiction (Garfinkel 111). Secondly, nano-doubters rely on .
             scientific fact to condemn nanotech. For example it is argued that we are very far away from ever seeing .
             nanotech due to the fact that when atoms get warm they have a tendency to bounce around. As a result .
             the bouncing atoms collide with other materials and mess up the entire structure (Davidson A1). Taken in .
             hand with the movement of electron charges, many regard nanotech as impossible (Garfinkel 106). But .
             this is not the entirety of the obstacles confining nanotech development. One major set-back is the fact .
             that the nanostructures are too small to reflect light in a visible way, making them practically invisible .
             (Garfinkel 104). .
             Nevertheless, Nanotech engineers remain hopeful and argue that; "With adequate funding, .
             researchers will soon be able to custom build simple molecules that can store and process information and .
             manipulate or fabricate other molecules, including more of themselves. This may occur before the turn of .
             the century."(Roland 30) There are other developments also, that are pushing nanotech in the right .
