The reverse engineering of the human brain is already well under way via new microchips and accompanying software. And, while full nanobot rewiring of the brain is not expected before 2020, It has been reported that our DNA has been successfully targeted by nanobots "for drug therapy or destruction."
Transhumanist Ray Kurzweil has been very open about the process that will take place as we head toward his projected date of The Singularity, while The Human Body version 2.0 continues apace.
It will be an incremental process, one already well under way. Although version 2.0 is a grand project, ultimately resulting in the radical upgrading of all our physical and mental systems, we will implement it one benign step at a time. Based on our current knowledge, we can already touch and feel the means for accomplishing each aspect of this vision. (emphasis added)In the video below, Kurzweil further articulates the relationship between our thoughts and our brains. Interestingly, he acknowledges the power of our thoughts as a creative force, even as he urges searching for the circuitry to control them. Despite the often benign language of futurists, we know that a concerted effort is already underway to manage and predict human behavior as well as control human memory. Our free will is being directly targeted. Ethical concerns must be voiced loud and clear.
