Francis Fukuyama argues that we are already in a posthuman world, largely because of pharmacokinetics, biomedical advances, and, specifically, prosthetics. Is there a point we will reach when there will be a separation of humans and cyborgs, as imagined by Philip K. Dick and others? If so, then what will be the line that separates the two? Along these same lines, is eugenics unethical? As we proceed forward into a blurring of biology with technology, is this helpful or harmful? Or does it depend entirely on how the technology is harnessed?
