Retired Prof. Agrees: We've Entered The First Stages Of A "Post-Human" FutureWe are now in the early stages of assembling individual atoms and molecules into nanomachines that operate in a nanoscale environment. Living cells are nanomachines engaged in ceaseless metabolic activities, taking apart and building molecules... The wall between machine and consciousness is gone. As we apply our technological prowess to the machinery of the human body and mind, we need to realize that we really are going down a path that has been until now regarded as science fiction. Do we today have the wisdom to settle on a good direction for our society at this tipping point in human history? Or will we just let the chips fall where they may?
