Again, how does your choice to alter parameters to achieve certain personality markers affect your state? Well, that depends on how you define the car. A machine is a device that amplifies human physical or mental capabilities in performing an operation (Machine). Deep brain stimulation involves implanting electrodes into the brain to induce changes to achieve clinical improvement in people with depression. Essentially, Theo will be perceived as part human and part machine because the electrodes receiving electrical stimulation amplify his mental abilities so he can function properly in daily life. In the event that Theo received the treatment simply to treat his depression, deep brain stimulation would act as a restorative technology that would work to restore Theo to his normal function and identity. In reality, this is not much different from using implanted cardiac pacemakers or artificial joints. However, if this treatment is taken a step further to optimize aspects of Theo's personality, then it turns into an enhancement technology, which can be perceived with a more negative aspect.
