Where are we going?, August 21, 2000
Foretelling the future, once the realm of mystics and entrail pullers, is now a subject of serious scientific study. Paul and Cox offer us a rational and plausible scenario of what the future holds for humanity. With backgrounds in biology and computer engineering, they've combined to bring competence to an enduring question: Where are we going? You may not like their view of the road ahead, but it's impossible to ignore their forecast. Their arguments focus on developments in neurosciences and computing power. They foresee a merger of these two disciplines resulting in the creation of a new humanity capable of engineering new, immortal physical brain carriers - bodies. Bodies themselves, as any gene can verify, are of minor importance. They are in essential agreement with Richard Dawkins that the selfish gene, in replicating itself, casts off the brain/mind of its host and losing whatever that mind has accumulated during its life. Their forecast is that the brain, using cybernetic technologies, will be able to avoid that waste by taking control of what DNA does during its thoughtless replication activity. This is a momentous proposal, worthy of serious consideration. The so- called 'moral' issues of whether humanity should engage in such activity, aren't shrugged off. Paul and Cox contend that there will be Rejectionists who will refused the option of cyberevolution and remain mortal. They suggest the Rejectionists will remain the chief source of art, music and other more diverse roles in life. We are left unclear as to how diverse the cyberhumans will become. The authors argue that the cyberhumans will be the ones to populate other planets, finding their diversity in response to new environments. The only real flaw in this book is ignoring the power of DNA in driving our lives and society. Whether we will ever understand the workings of DNA sufficiently to actually create a wide range of individuals remains problematic. The individual who first successfully transforms into a cyberhuman will set a pattern more likely to be repeated than modified. To create discrete cyber-individuals will be tremendously resource extravagant. This is likely lead to a narrow range of available DNA to launch the cyberpopulation. As we have already experienced with the shrinking gene pool of crop seeds, such a reduced variety is highly vulnerable to virus assault. An organism that succeeds in infecting such a limited diversity can quickly wipe out the whole cyberhuman population. Modifying the gene pool to resist such an infestation will take more resources and the Rejectionists will again be successful survivors through their genetic diversity. This flaw, however powerful, doesn't detract from the significant questions raised and developed in this compelling book. If you wonder about the future, if you think computers are only for entertainment, if you think humans are the logical end of evolution, then buy and read this fascinating book.
