The human ability to learn and adapt is what sets us apart from all other creatures. We are the self-aware learning animal. We are the only social group that can determine its own evolution. With that role comes a responsibility to shape who we will become mentally, morally, socially, and physically.
In defining our future, I agree with Greg Ulmer that we are in a transitionary period of human history, and that contemporary information storage and retrieval systems will change humanhood at a core level. We have been shaping our future at a deep level for quite a while now. Survival of the fittest has been replaced by survival of the richest. Those with access to technology can repair themselves (extending their life) and alter their appearance (increasing chance of propagation). This is a limited example, but points to our newfound deviation from Darwinian survival-of-the-fittest. We are already controlling some evolutionary variables. We have even largely removed some, like poor eyesight. There was a time when having very poor eyesight would limit what you could do for work, and lessen your chance to have children. Left un-corrected poor eyesight might naturally dwindle through the generations, but poor eyesight is no longer a challenge. We are now stuck having poor eyesight until we can correct it at a genetic level that will propagate to our children. We are stuck correcting genetics with technology in a huge number of ways. We have arrested the mechanism that brought us to where we are now. An expansion on these ideas and their consequences can be found in the book "Our Posthuman Future."
We have already defied Darwin, now we accept it and move forward responsibly. What is there to gain in this transition? Very old problems can be rethought for new solutions. Is there one major change that can be brought forth during this shift to propel us healthfully into the future? An intelligent society. We have to shape who we will become, because it will not happen for us anymore. I would like to give future generations a right to access all information.
