In his book Radical Evolution: The Promise and Peril of Enhancing Our Minds, Our Bodies—and What It Means to Be Human (2005), author-journalist Joel Garreau identifies four technologies whose synergistic activity may transform humankind into a state transcending present human nature: genetic, robotic, information, and nano (GRIN) technologies. If the GRIN technologies follow Moore's Law, as information technology has done for the past four decades, Homo sapiens and human society may be unimaginably different before the middle of this century. But (...) among scientists, futurists, and other pundits there is no agreement on the nature and ramifications of this transformation. Based on dozens of interviews, Garreau sees three possible scenarios for our species. The Heaven Scenario foresees enhanced bodies and minds in a disease-free world, perhaps even immortality; the Hell Scenario warns of losing our identity as a biological entity and perhaps the demise of liberal democracy; the Prevail Scenario predicts that we will muddle through the GRIN technology revolution basically intact, as we have prevailed during past technological upheavals. In this review, these scenarios are examined in the context of Kuhn's “normal” versus “extraordinary” science and in the context of current understanding about gene function. (shrink)

An exploration of the moral and ethical implications of new biotechnologies Many of the ethical issues raised by new technologies have not been widely examined, discussed, or indeed settled. For example, robotics technology challenges the notion of personhood. Should a robot, capable of making what humans would call ethical decisions, be held responsible for those decisions and the resultant actions? Should society reward and punish robots in the same way that it does humans? Likewise, issues of safety, environmental concerns, and (...) distributive justice arise with the increasing acceptance of genetically modified organisms in food production nanotechnology in engineering and medicine, and human gene therapy and enhancement. The problem of dual-use—when a technology can be used both to benefit and to harm—exists with virtually all new technologies but is central in the context of emerging 21st century technologies ranging from artificial intelligence and robotics to human gene-editing and brain-computer interfacing. In Re-Creating Nature: Science, Technology, and Human Values in the Twenty-First Century, James T. Bradley addresses emerging biotechnologies with prodigious potential to benefit humankind but that are also fraught with ethical consequences. Some actually possess the power to directly alter the evolution of life on earth including human. Specifically, these topics include stem cells, synthetic biology, GMOs in agriculture, nanotechnology, bioterrorism, CRISPR gene-editing technology, three-parent babies, robotics and roboethics, artificial intelligence, and human brain research and neurotechnologies. Offering clear explanations of these various technologies, a pragmatic presentation of the conundrums involved, and questions that illuminate hypothetical situations, Bradley guides discussions of these and other thorny issues resulting from the development of new biotechnologies. He also highlights the responsibilities of scientists to conduct research in an ethical manner and the responsibilities of nonscientists to become “science literate” in the twenty-first century.
