Science journalist Ronald Bailey claims that McKibben's historical examples are flawed and support different conclusions when studied more closely. For example, few groups are more cautious than the Amish about embracing new technologies, but, though they shun television and use horses and buggies, some are welcoming the possibilities of gene therapy since inbreeding has afflicted them with a number of rare genetic diseases. Bailey and other supporters of technological alteration of human biology also reject the claim that life would be experienced as meaningless if some human limitations are overcome with enhancement technologies as extremely subjective.
