 I agree with Perspective Three that the true impact of intelligent machines in our lives is that they challenge us to re-think our preconceived notions of what people can do or become in the future. A final example of this is brain-computer interfaces, or BCIs. Humans are able to manipulate computers with their brains via electrodes that are either implanted in their brains or attached (temporarily) to their heads. With these intelligent machines, formerly paralyzed people who had no hope of communicating with others are able to transcend their physical limitations by concentrating to form words out of keyboards on the computer screens. In addition, BCIs have captured the interest of people from all different backgrounds and are being applied to non-scientific fields like music to create new, previously unimagined instruments that react to people's thoughts, adding a new dimension to an ancient art form. Truly, intelligent machines are providing the impetus not just for greater efficiency, but for greater accomplishments.
