I decided to research the question ‘What does it mean to be human?I because of an idea put forth by one of my professors. He suggested that our idea of what it means to be human has evolved with technology. With such basic things as glasses, wheelchairs, and now prosthetics and biotechnology, we are a hybrid mix of the human and the technological. This particularly interested me because I was aware of the amazing breakthroughs in stem cell research, and I wanted to know how such developments may change our understanding of humanity. For example researchers are working on growing human organs in the lab. Regenerative medicine is a natural way of replacing human tissue, in that it involves no inorganic material in the integration process. These breakthroughs in medical engineering require us to analyze technological progress and how it impacts the human body. We should hold these new technologies at arm’s length with the knowledge of what past technological advances have resulted in, analyzing their possible end results and what those results could eventually do to the human body. We are fundamentally changing what it means to be human.
