One vector is cognitive enhancement using pharmaceuticals, genetic therapies and tissue engineering. Direct modification of the organic brain will allow human beings to increase our intelligence, expand our memory, sharpen our capacity for concentration, and eliminate cognitive and psychological disabilities.
A second vector is through ‘cyborgization’ - the incorporation of devices, nanorobots and computers into the body. This trajectory may permit the augmentation of the senses with artificial hearing and sight superior to organic ears and eyes, the direct augmentation of cognition with brain prostheses, and connecting the brain wirelessly to the Internet. These technologies will likely converge with the growth of virtual worlds and augmented reality, blurring divisions between the “virtual” and the “real.”
The third vector of human enhancement is through the creation of ‘mind-children,’ computers and robots with, at least, human-level cognition, emotions and abilities. These machine minds may be created either through efforts to create artificial life and general intelligence, and/or by uploading human minds into machines. Once created these machine minds may be far more capable and powerful than organic humans."
