McLuhan believed that technology is in a way, an extension of a human because it can be create “roles” for people such as the level of involvement they have to their work. McLuhan gave a great example of such concept with the electric light, he talks about the uses of the electric light in setting such as it being used during a brain surgery or night baseball, all of which is indirectly a function of the electric light or and extension of it much like how technology can indirectly extend the capabilities of a person. Such example was given in the “Understanding Media: The Extensions of Man” by Marshall McLuhan “Positively, automation creates roles for people, which is to say depth of involvement in their work and human association that our preceding mechanical technology had destroyed”…..”Whether the light is being used for brain surgery or night baseball is a matter of indifference. It could be argued that these activities are in some way the “content” of the electric light”.

Technology itself despite all the benefits, also possess a equal amount of negative aspects to it. Just like how it can be an extension to a person by allowing more functionality, it can also lead to a decline in the specific professions in which machines are more than capable of substituting. Although such events are possible and has occurred, these changes are more of something natural to occurred as most lost of jobs are primarily works that can be elevated to greater heights with the use of machine and some cases have people manning said technology to increase the output of said task.
