Here's a Christian manifesto on combating the siren song of transhumanism; it isn't for nothing that Ken MacLeod calls the Singularity the "rapture of the nerds," it really represents a kind of secular, techno-transcendentalism. It's not just reactionary hand-wringing, either; there's some meaty questions about bioethics, a transhuman divide between the rich and the poor; gene patents, and the rights of uplifted organisms:
Where biotechnology is ultimately headed includes not only redefining what it means to be human, but redefining subsequent human rights as well. For instance, Dr. James Hughes, whom I have debated on his syndicated Changesurfer Radio show, wants transgenic chimps and great apes uplifted genetically so that they achieve "personhood." The underlying goal behind this theory would be to establish that basic cognitive aptitude should equal "personhood" and that this "cognitive standard" and not "human-ness" should be the key to constitutional protections and privileges. Among other things, this would lead to nonhuman "persons" and "nonperson" humans, unhinging the existing argument behind intrinsic sanctity of human life and paving the way for such things as harvesting organs from people like Terry Schiavo whenever the loss of cognitive ability equals the dispossession of "personhood." These would be the first victims of transhumanism, according to Prof. Francis Fukuyama, concerning who does or does not qualify as fully human and is thus represented by the founding concept that "all men are created equal." Most would argue that any human fits this bill, but women and blacks were not included in these rights in 1776 when Thomas Jefferson wrote the Declaration of Independence. So who is to say what protections can be automatically assumed in an age when human biology is altered and when personhood theory challenges what bioethicists like Wesley J. Smith champion as "human exceptionalism": the idea that human beings carry special moral status in nature and special rights, such as the right to life, plus unique responsibilities, such as stewardship of the environment. Some, but not all, believers in human exceptionalism arrive at this concept from a biblical worldview based on Genesis 1:26, which says, "And God said, 'Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.'"
