I found this chapter to be very mind-opening, as I never classified people with implanted pacemakers or cardioverter-defibrillators as “cyborgs” or “hybrids”. Nonetheless, perhaps my perception of them as “regular” humans relates to my lack of knowledge about the function of these devices, and the effects they have on their “bearers”. The aforementioned introduces the newly developed concept of ontology, which states that bodies and technology are co-producing one another. Therefore, once one becomes a cyborg, there is no return to their old body state. This is further clarified by Pollock, who stated that, “There is no self that is independent of the device; the patients and defibrillators are one”. However, to properly classify patients with these devices, one must analyse their embodied sensory experience. Once inserted inside the body, the patient cannot independently control the function of the device, as the electric pulses and shocks take over the rhythm of the heart. The only person capable of changing the machine’s current is the technician through the use of a programmed computer. This in turn affects the way the patient carries on with their lives, as many of them complained about how the ICD or pacemaker does not necessarily correspond to the way they live, hence demonstrating how these people are less able to get a hold of their bodies. For instance, some patients expressed how the inappropriate adjustment of the pacemaker leads to feelings of tiredness, especially during physical activity. As well, other patient expressed how they needed to pay close attention to the beeping sound made by the machine as an indication of its malfunction. The aforementioned illustrates how the hybrid needs to become more intimate with their hybrid materiality to carry out a successful life. The patient needs to be aware that it is not only their heart that is dependent on the machine, but it is their life itself. Consequently, the bearers of these machines grasp that they are no longer in total control of their body, but the machine is, hence the establishment of the resemblance between cyborgs. This idea seems fascinating to me, as the use of technology has always been defined and finite for human beings. Nonetheless, this is not currently the case, as internal technological devices are what decide how the body will be utilised.
