וזאת מסקנת המאמר:
Thus, the preceding observations paint a rather stark picture. At least in highly industrialized societies, the impact of deleterious mutations is accumulating on a time scale that is approximately the same as that for scenarios associated with global warming—perhaps not of great concern over a span of one or two generations, but with very considerable consequences on time scales of tens of generations. Without a reduction in the germline transmission of deleterious mutations, the mean phenotypes of the residents of industrialized nations are likely to be rather different in just two or three centuries, with significant incapacitation at the morphological, physiological, and neurobiological levels. Ironically, the genetic future of mankind may reside predominantly in the gene pools of the least industrialized segments of society. Possible solutions to this problem, including multigenerational cryogenic storage and utilization of gametes and/or embryos, will raise significant ethical conflicts between short-term and long-term considerations.
