The extraordinary claim that the technological enhancement of the human brain's neocortex will make us more "godlike" suffers from a mistaken comparison between God and human beings. God is not a super-creature among creatures. The characteristics traditionally predicated of God with respect to knowledge, power, and love, for example, are not possessed by God in a greater degree than they are possessed by human beings. When we use terms such as omnipotent, omniscient, and all-loving when referring to God, we must remember that all such language about God is at best analogical and that, finally, God transcends all such categories. The temptation to be "like God" is an old one, and it always needs to be resisted, even in its modern technological guise.
Folks like Kurzweil strike me as having a thinly-veiled contempt for humanity, as if what we are is "merely" human, that humanity is and always will be inferior to machines, and that the creations of man (that is, machines) are in some way more virtuous than humanity itself, and so the worship of the machine is founded upon a form of self-loathing, Kurzweil despising himself for being an animal, an ape, a man. After Nimrod built his tower, when he climbed to the top he was astonished to find that he was no nearer to heaven, that the god of Abraham remained beyond his grasp forever.
Wait, wait: this isn't about reading or writing, is it? No, it's not directly, but I am planning a novel featuring a philosopher, so I will be thinking a lot about philosophy and the metaphysics of humanity for the next several years. Tomorrow, though, if I find time, I will post about Out of Africa.
